Review Of The New Dwarf Mini from Dwarf Lab

The new Dwarf Mini is proof that great things really do come in small packages. Holding the title of the world's smallest smart telescope, this remarkable little instrument weighs less thank 2 pounds yet delivers an astrophotography experience which would have seemed impossible just a few years ago.

Dwarf Lab - the ones who brought us the amazing Dwarf 2 and Dwarf 3 smart telescopes; which I’ve also had the pleasure of testing and reviewing below…have once again managed to push the boundaries of what's possible in a portable AP system.

The Dwarf Mini has the unique distinction of being the world’s smallest smart telescope. At only 840 grams (~1.85 lbs). At 3.9" x 7.2" x 2.4" it’s small and light enough to fit in a sweatshirt pocket. It beats all currently available smart scopes on the portability factor. If portability is high on your list of priorities, then you simply can’t beat The Dwarf Mini. 

Some Major Stats:

The Dwarf Mini is comprised of: 

• A six-element astro-optimized optical design
• It features a Sony STARVIS 2 IMX662 sensor

• 150mm F/5 apochromatic telephoto lens
• 6.7mm (45mm equiv.) wide field lens, which provides a 60 Degree FOV
• Magnetic solar ND filter
• EQ Mode
• Mosaic mode
• 64GB internal storage
• Dual-band Wi-Fi (2.4GHz & 5GHz)
• Bluetooth 5.0
• USB-C connectivity

Let's move on to packaging - and unboxing -

As is typically the case with products from Dwarf Lab, the unit arrived very well packaged; small but sturdy boxes were used, and all items were double boxed.

You will find the current retail price of The Dwarf Mini to be around $399 US dollars.

Features - similar to both The Dwarf 2 and The Dwarf 3 smart telescopes, The Mini boasts quite a few features:

• A 7000 mAh battery with USB charging port
• 4 hours of battery life
• The ability to polar align, for longer exposures
• Included custom carry case with adjustable strap
• One step / Built-in post processing - Stellar Studio
• Temperature range of operation: from 14 Deg. F to 140 Deg. F 

This last feature is of considerable interest to me. When I used The Dwarf 3 this past Winter (here in upstate NY) the unit began to exhibit some issues when the temperature dropped to around 32 Deg. F. I was surprised because The Dwarf 3 was also rated to operate at temperatures as low as 14 Deg. F. However, at 32 Deg. F, it began to experience the issues which the documentation listed as things that happen at (below) 14 Deg. F. Mainly, the inability to recognize/draw battery power, and unable to continue imaging. This was disappointing…Okay, back to The Dwarf Mini…

Holding The Dwarf Mini 

Among the features that I find the most interesting are: 

• The ability to schedule imaging sessions - very easy to do also.
• 'Astro' Filter: 430-690nm Enhances nebulae contrast (by enhancing sensitivity to infra-red). 
• 'Duo-Band' Dual Narrowband Filter - HA 656.3nm and OIII 500.7nm (cuts moonlight, city glow and light pollution).
• Up to 90-second exposures with tripod and polar alignment.
• The ability to power down the unit remotely.
• How easy it is to polar align - Especially if you use the hack from this YouTuber:

In the interest of transparency and full disclosure, the above hack doesn't differ too much from the official EQ Mode instructional video provided on The Dwarf Lab site.

As can be seen in photos online, The Dwarf Mini sports a very slick design. I like it very much! Molded in a very nice-looking charcoal gray. Let's not forget, when used in Alt-Az mode, a tripod isn't even needed - It may simply be placed on a sturdy, flat (and preferably level) surface - and away you go!

In use - I find The Dwarf Mini super-easy to use - Generally speaking, we’re looking at the same 3-4 steps which other (affordable) smart telescopes use:

• Place outside and power on.
• Open arm and allow The Mini to calibrate itself.
• Choose your target object.
• Click the shutter button to start shooting.

I've been very impressed by the auto focus. It works well, is accurate, and doesn't take very long at all. This is a welcome change, after using smart scopes which seemed to take forever to auto focus. If we're being honest, when you're anxious to acquire images, any delays are very unwelcome!

As outlined above - Since it's so easy to use, The Dwarf Mini would be ideal for just about anyone with an interest in astrophotography. It helps if the end user is familiar with technology, or at the very least, navigating their own cell phone or tablet. Luckily, I believe that would include most people!

If you've always wanted to try taking pictures of the night sky, the Milky Way, deep sky objects, and the Sun then this would be an excellent choice for you. One of the stand-out aspects of The Dwarf Mini is it's ease of use - going from unboxing -to- taking images, in a very short amount of time. No real steep learning curve here.

The Iris Nebula - A beautiful reflection nebula.

A typical night under the stars for me, involves taking full advantage of it's remote control capabilities.

I set the unit up outside on an outdoor table, power it on, select an object, and start imaging. Since I'm someone who deals with chronic pain, I typically retreat back indoors, to control everything via my iPhone (WiFi). This works very well for me, especially having the optional wide field view whenever I need it.

If you try to get every last bit of battery life from it: You'll find that it stops imaging operations as soon as the unit's battery level reaches 7%. It stops taking photos, and waits for user input. When it first happened, I thought "Hmm...this is interesting; you can only get to 7%..." However, this seems like a good engineering design. I'd rather know that 7% battery life is the cut off time, than the possibility of having images get corrupted or not saved.

As with all smart telescopes, I recommend getting yourself one or even two external USB battery packs (the rechargeable ones everyone uses). Be sure to plug one in even before your unit approaches the 7% battery mark.

I have been struck with the overall accuracy of the unit. I have not found it to be "off" in any way: If it states it's pointed at an object, it really is pointed there. The Wide Frame Window was in alignment out-of-the-box. This small, wide field of view window, allows you to quickly see the wider "picture" of where the telescope is pointed.

When I saw this feature on The Mini, for the very first time, I didn't think much of it. In fact, I didn't think it would be of much use to me. Now, I don't know how I could get by without it! In a way, it provides you with some peace of mind - knowing that you're pointed in the right place. It is also very useful for keeping an eye on any clouds which may be sneaking in. Also, if for any reason you prefer not to see it - simply click on it, and it disappears. 

M27 in 49 minutes and 45 seconds - A lovely result.

Pros:

• Super small and easy to deploy and use anywhere!
• Very easy set-up steps - Take you from 0 -to- imaging in no time!
• The Wide Frame Window - Allows you to see the wide FOV of the area you're focused on at a glance.
• The Apochromatic optics produce wonderful, sharp results with your astrophotos. 
• Polar alignment is very easy.
• Virtually One-step post processing via Stellar Studio / Dwarf Lab's cloud.

Cons:

• Battery life doesn't go to 4 full hours
• After locating your target, the unit must initialize for ~30 seconds or so. 

If you're expecting 4 hours of battery life, you'll probably be disappointed. I didn't get a full 4 hours during my tests.

In regards to the 2nd Con: I've at least learned that several important functions/activities are taking place during those ~30". So, I guess I should learn to be more patient!

In addition to the 2 imaging filters available (Astro & Duo Band), The Dwarf Mini also has a built-in dark field "filter" which enables the unit to create dark field exposures for automatic application.

These dark exposures (or Darks as we call them) are available for those who are inclined to do their own stacking, etc., outside of the unit. On a laptop, or PC, etc. Of course, you can have access to the individual sub exposures as well.

The lower half of The North American Nebula - It reads unknown, because I chose the aim point myself.

One of the features which drew me to The Dwarf Mini, was it's price. At a typical price of $399, it is the most affordable smart telescope available. It may be ordered directly from this affiliate link I've recently been provided - If you order using this link, I receive a small commission; at no cost to you. 

The Heart Nebula.

 

I've been fortunate enough to test and review several affordable smart telescopes so far. In summary, I'd state that I really enjoy using The Dwarf Mini. The software App is robust and easy to use. All things considered, the only real "Con" of any significance, is the slightly-less-than 4 hour battery life I experienced. I really can't find anything else to complain about with this unit. It delivers on all it promises.

The resulting images of deep sky objects speak for themselves! All of the images shared above, were straight out of the telescope, after just applying the Auto (Denoise, etc) feature built in to The Mini's Stellar Studio. No other post processing was done. I've honestly found that additional processing is not actually needed. All in all, I really, really like The Dwarf Mini! I've been loving the impressive results. I've even found it to capture small planetary nebulae well.

What Dwarf Lab has accomplished is remarkable. They've managed to package a capable astrophotography system into something small enough to take virtually anywhere. Whether you're a complete beginner looking for your first smart telescope or an experienced astronomer searching for the ultimate grab-and-go imaging companion, the Dwarf Mini is easy to recommend.

Finally...This may seem like a touchy subject, but... I've recently received The Seestar S30 Pro; and The Dwarf Mini has been holding it's own in side-by-side comparisons - Truly amazing! Especially when one considers the much higher price of The S30 Pro. 

Going forward, I may be making some minor additions and updates to this review.

Until next time...

Stargazing Starts Where You Are: Why the DWARF mini Approach Matters

“When you really love a hobby, you genuinely want to share it with as many people as possible”

-Al Milano 😉

For many people interested in astronomy, the biggest obstacle is not curiosity — it’s complexity.

Traditional astronomy can feel intimidating at first:

• heavy equipment

• confusing setup procedures

• polar alignment

• complicated software

• expensive gear

• and the constant feeling that you need the “perfect” dark-sky location before you can even begin.

That’s exactly why I find the emerging direction behind the DWARF Mini so interesting.

The company is preparing a new “First Night Kit” initiative built around a simple but surprisingly important idea:

Stargazing Starts Where You Are.

And honestly, that message resonates.

Because the reality is that most people do not begin astronomy from a remote desert observatory under pristine Bortle 1 skies.

They start:

• from a backyard

• on an apartment balcony

• at a campsite

• from a driveway

• or from whatever ordinary location they already have access to.

That first experience matters enormously.

If the setup is frustrating, overwhelming, or overly technical, many beginners simply give up before they ever experience the magic that got them interested in astronomy in the first place.

The appeal of compact smart telescopes like the DWARF Mini, is that they attempt to lower that barrier dramatically.

Portable, approachable astronomy has become one of the most important trends in the hobby over the past few years. Devices like the DWARF Mini are designed around the idea that astronomy should fit into real life — not require completely rearranging your life around the equipment.

Again, we must keep in mind that we’re talking about first time beginners here. Experienced amateur astronomers and Astrophotographers, like myself and many of you: we actually enjoy some of the complexity required with full traditional Astrophotography rigs. They not only offer a challenge, but many of the advanced features are very neat!

Getting back to the subject of portability, when using compact, smart telescopes - That portability changes the experience in practical ways:

• easier spontaneous observing sessions

• faster setup times

• less intimidation for beginners

• easier travel

• simpler sharing with family and friends

And perhaps most importantly, it encourages people to actually use the telescope more often.

Because the best telescope is still the one you’re willing to take outside.

What I particularly like about the “Stargazing Starts Where You Are” philosophy is that it acknowledges something experienced astronomers sometimes forget:

Beginners do not need perfection to become excited about astronomy.

They need success.

They need a first nebula.
A first galaxy.
A first Moon image.
A first moment where the night sky suddenly feels personal and accessible rather than distant and technical.

That first successful experience can become the foundation for a lifelong hobby.

Will a compact smart telescope replace large traditional astrophotography rigs? Of course not.

But that misses the point entirely.

The goal here is accessibility — creating a realistic and enjoyable entry point for people who may otherwise never take the first step into astronomy at all.

And in that respect, the direction behind the DWARF mini feels very aligned with where the hobby itself is evolving:

• simpler

• more portable

• more approachable

• and more connected to how people actually live.

Because in the end, astronomy doesn’t have to begin at a dark-sky observatory.

Sometimes it begins exactly where you already are. 

Until next time,

Clear skies!

Review: The Dwarf 3 Smart Telescope

The Dwarf 3 Smart Telescope

“There are only two ways of looking at the world: one is as if everything is a miracle, the other is as though nothing is”

- Einstein 

I can say right from the beginning, that I am very grateful for the existence of The Dwarf 3; and for that matter, smart telescopes in general.

They truly are little miracles. 🔭 

Let’s start by having a look at how The Dwarf 3 arrived to me, here in New York.

I purchased the complete package, with optional Dwarf Tripod, directly from DwarfLabs.

Unpacking The Dwarf III

It is 222 x 142 x 65mm in size, and weighs only 2lbs 14Oz (1.3kg). The optional tripod adds 1lb 7Oz (0.65kg), while the carry case is 21Oz (0.6kg.). Making the full kit is very easy to carry and manage.

I would urge you to have a look at the neat comparison chart (Dwarf 3 vs Dwarf 2) which may be found by scrolling down on this DwarfLabs page It shows all the major features, side-by-side.

As ordered, with the optional tripod, the total cost to me (here in New York, USA) was $629 US Dollars. It's actually going for a little less at the time of this writing. As always, I would encourage the reader to shop around for the best price.

The major features include: 

A larger 35mm diameter apochromatic objective, along with a larger 3.4mm wide field lens. 

A longer 150mm focal length. 

A Sony IMX678 Starvis 2 imaging chip.

The overall exterior design may be described as a slightly larger version of The Dwarf 2. As with The Dwarf 2 (and every other smart telescope) it is controlled by your iOS smartphone, tablet, or Android device. The software is fast and free to download, and is also being improved from time to time. It's called The Dwarflab app. The controls are conveniently located on screen, and as of November 2025, include: General Mode, Deep Sky, Solar System, Auto-Capture, and Pano.

General Mode enables access to: Photo, Burst, Video and Time Lapse.

Just pulled indoors after an imaging session

I found it very easy to use, but requiring a bit of patience at times: The unit must calibrate itself for a couple of minutes, after locating an object. In my case, it's always DSO's!

The Dwarf 3 would be ideal for someone who would like the ability to get involved in their astrophotography. It is designed to allow the user (if willing) to:

• Select and stack their own sub frames (individual exposures) within the built-in Stellar Studio App.
• Export and stack the subframes in a (non-Dwarf) application of their choice (DeepSkyStacker, etc.).
• Tinker with the different exposure settings (when acquiring images).
• On board photo adjustments are also available while imaging DSO's, such as curves, etc. Although I found them to be too drastic/dramatic when I experimented with them. 

Just a quick shot of a section of Milky Way

(very little post processing applied)

It also features the ability to take very nice Milky Way shots. It is provided with appropriate solar filters for taking convenient images of the Sun. As well as daytime photos of wildlife, etc. I haven't used these features yet (DSO's are always on my mind!).

I will mention, that I've tracked down and imaged several planetary nebulae with it - and although it's not ideally suited for this, I was satisfied with the results on the (slightly larger, non-Messier) planetary nebulae. 

I found the overall accuracy of it's goto abilities to be satisfactory. The unit features overnight scheduling ability: 

For example: Program it to image Object A for 1 hour, Object B for 30 minutes, Object C for 2 hours, then shut down. Pretty neat!

Pros:

• Compact and easily portable.
• The user can choose to be involved in the astrophotography process, by utilizing Polar alignment and 3rd party stacking software.
• Good value for what you get: It's quite versatile.
• Everything is easy and fully automated.
• Includes Megastack - The ability to stack previously stacked results, into one combined final image.
• Proven to have excellent wireless range, and robust enough to be left out all night.

Cons:

• App has frozen on occasion.
• It does take a couple of minutes, from locating object (DSO) to commence shooting.
• My (low budget) iPhone SE displays warning messages about not having enough space - luckily, it still functions anyway. Users with newer/more capable phones and tablets will be fine.

In summary, there's no denying that this new Dwarf 3 produces! 

I've seen many outstanding imaging results, from users across the country (here in The US). Some users may choose to participate in the astrophotography workflow by performing polar alignment and using third-party stacking software - When coupled with good exposure times (~1-4 hours) the resulting DSO images have been stunning!

The Dwarf III has acquired the nicest looking result of M45 I've ever seen from any previous (affordable) smart telescope; and in only 6 Min. 15".

After acquiring your stacked image, you upload it to the Dwarf Labs' cloud (Stellar Studio), select what you'd like done (I always choose Auto), and in a few minutes, the image appears, fully enhanced!

I was just the slightest bit "skeptical" at first myself, but the results speak for themselves.

Here is an image of M16, with only Star Correction applied.

It's fun to have the different options to choose from when using the built-in Stellar Studio App! In my experience (of only a few months) I've always relied on Dwarf Labs' (built-in) Stellar Studio (cloud based) tool for final processing. I have been more than satisfied with the results. I believe it may have spoiled me! The results have been so good, that I don't even use any 3rd party stacking/processing app - However, I am definitely looking forward to trying some!

It's convenient to have the subframes available (located in the telescope itself). Since there are some images I'd really like to put some more effort into...

The Soul Nebula, in under 30 minutes!

If you'd also like to see just what The Dwarf III is capable of, have a look at the results obtained by Dwarf 3 owners in the Dwarf 3 online communities and groups (Facebook has several).

You will come across some amazing results from other amateurs. The hobbyists who have dedicated several hours of exposure time per object.

Polar aligning The Dwarf 3, opens up a world of possibilities resulting from longer sub-exposures.

I am planning on adding some more updates and details to this review, so check back from time to time…

Some Dwarf 3 owners are using serious tools like PixInsight; and utilizing various palettes, and have created stunning end results. In any case, The Dwarf 3 certainly deserves a closer look!

Clear skies!

Review Of The Dwarf II Smart Telescope Part 1 of 1

Here is my full Review of The Dwarf 2 smart telescope.

The Dwarf II is the smallest, lightest, and most portable of all the smart telescopes available today. It also happens to be the most budget-friendly! At it's current (on-sale) price of only $459 - It is the lowest-cost smart telescope currently available! It is basically a user-friendly, entry-level, introduction to astrophotography! One which the entire family may enjoy.

An interesting point to note: Is that The Dwarf 2, provides a user with an actual "taste" of real (conventional) astrophotography - but with the most annoying factors omitted! It's safe to say, that all of the other smart telescopes on the market don't. Rather, all of the others (many of which can get expensive!) are devoid of any bits of the astrophotography experience. In other words, all of the other auto-telescopes are completely automated. Removing the user from the experience (or process) altogether. This is a very interesting point to consider.

If you'd like to see a few pics from the day The Dwarf II arrived; and was unboxed, then have a look at this post.

The Dwarf II measures 204 x 62 x 130mm or 8 x 2.4 x 5.1 inches. And weighs only 1 kg or 2.4 Lbs.

It's main features are that it is:

• It's super small / compact
• Controlled by your smartphone (or tablet) / Android or iPhone based.
• Object GOTO ability / and Automatic star tracking
• Automatic stacking of your images from space.
• Ability to do daytime photography (and video), as well as panoramic images.
• Comes with rechargeable battery & 64GB MicroSD card.

I'll be covering these features in more detail, sometime later in this review. Additional technical specifications include:

• A formidable resolution of 8.46 Megapixels
• Pixel size of 1.45um
• A 24mm lens aperture, @F/4.2, 100mm refractor
• Utilizing a Sony IMX415 sensor chip

All things considered, it is fairly easy to use. The thing to keep in mind, is that The Dwarf 2 is not a fully-automated smart telescope. Again, it is designed to allow the user some involvement in the astrophotography process.

But, I can promise you, it isn't a lot! The learning curve is not steep at all. Typically, by the 2nd night out, you'll be well-versed in it's proper operation. By the 3rd or 4th night out, you'll be an expert!

This makes The Dwarf II ideal, for someone wanting to do some astrophotography of DSO's (Deep Sky Objects) without having to learn or study the subject.

Next, I'd like to draw your attention to the things which are required for normal astrophotography. The stuff one must do in the traditional hobby... 

Things like Polar alignment. Something which is a must, when doing conventional astrophotography. Many astrophotographers (myself included) are not fond of polar aligning a set-up. Depending on your equipment, it can be quite annoying. As evidenced by the existence of so many funny memes on the subject!

Things like:

• (1.) Polar alignment - Not needed, but optional with The Dwarf 2. If you chose to, it is easily done.
• (2.) Having to take Calibration frames: Darks, Biases, and Flats - Oh my!
• (3.) Monitoring of the progress.
• (4.) Having an autoguider to purchase, and then worry about.
• (5.) Having to wait until the next day (typically) to sort through, organize, and stack your frames.
• (6.) Stacking and post-processing "your data" - this necessitates being in front of a computer screen, for substantial lengths of time (always my least favourite part).

Below, I've provided detailed explanations of each component:

1. Polar alignment - Aligning your telescope's mount, to the star Polaris, "the North Star" in the Northern hemisphere. Or the Southern Celestial Pole / the 4 stars of The Southern Cross constellation; if you live in the Southern hemisphere.

2. Calibration frames - 

Darks: A series of (anywhere from 20 to 60) exposures taken for the same length of time as your Lights; with the lens cap on.

Biases: Similar to above, except using the fastest shutter speed your camera is capable of. 

Flats: Similar to taking Darks, except with a white T-shirt stretched over the front of the lens, while aiming at a uniform source of illumination. Such as a slightly overcast sky during the day.

3. Frequent checking, on how everything is going. More specifically, things like: Is the system still tracking properly? eg. Are the stars still round? or are they beginning to trail? If so, that's more frames for you to discard when you're going through them later... A moot point with The Dwarf II!

4. Autoguiders! An autoguider is a smaller telescope, equipped with it's own small (CMOS or CCD) camera - you center it on a star, and it communicates any tracking corrections needed to the main imaging system.

Well, as I have a habit of being honest to a fault: I will state, that I've been intrigued by autoguiders over the years. However...There are some things to consider: In order to use / take advantage of an autoguider, your set-up needs to be a certain level of capability. In other words, if you're not using an advanced tracking mount to begin with, an autoguider cannot be a consideration. Less expensive tracking mounts simply don't feature an autoguiding port.

If you do have a top-of-the-range tracking mount; then you can purchase a small guidescope and guide camera. Which will ensure that your tracking mount avoids tracking errors, etc.

Okay, all of that 🠉 doesn't exist with The Dwarf II.

5. Yep, all shots - Lights*, Darks, Biases, and Flats must each be placed in their own, dedicated file folders. Later, each folder must be specified (you must inform your software where each folder is). Or, things will not go well for you - LoL!

However, I'll state that it's inherent versatility, allows a user to get as involved as they please. Again, optional - as in, if a user is so inclined to. I'll touch on this a bit more below.

6. This is the part where your software has already stacked all of the (various types) of frames. This is when and where your post processing (of the final image) takes place. This was always one of my least favourite parts. It consists of sitting in front of your computer screen; and applying one minor adjustment after another to your final picture.

After one becomes competent (proficient) in this skill, they develop what is referred to as a workflow. Essentially, a series of steps of adjustments to your final image, which further enhances and sharpens your final result.

If someone were to ask me: Who is The Dwarf 2 good for? I would say (1st and foremost) it's well-suited for anyone wishing to try astrophotography. Virtually anyone from a (patient) teenager to a seasoned/experienced astronomer would likely enjoy this smart telescope. The only prerequisite being a desire to photograph objects in the night sky. 

It is especially well-suited for anyone who has tried some astrophotography in the past, but perhaps found a facet of it annoying, unpleasant, or tedious. Since what a smart telescope does, is effectively handle almost all of the boring stuff! Why do I use the term almost? because in the case of The Dwarf 2, some things are still possible (at the user's discretion).

The unique thing about The Dwarf 2, is that it doesn't do away with everything. It gives the user the optional opportunity to:

• Attach 3rd-party nebula filters, including experimenting with various narrowband filters (Ha, OIII, or SII).
• Attach it to a standard, adjustable photo tripod, to do a (simple) polar alignment. This will allow you to accomplish much, much longer imaging sessions, before the effects of field rotation become apparent. 
• Take their own (additional) calibration frames (Darks, Flats, & Biases) to manually stack in software later. Someone might do this, in an effort to "squeeze" every additional amount of image quality out of the unit's capability. Think of this as something an experienced astrophotographer would be apt to do.

For my part, I have purchased an excellent nebula filter...What I'm actually referring to is called a Duo Band filter. I bought it from High Point Scientific. 

Until next time,

Clear skies!

Review: The AM3 Harmonic Drive Mount and TC40 Tripod from ZWO - Part 2 of 2

Review: The AM3 Harmonic Drive Mount and TC40 Tripod from ZWO - Part 2 of 2

Once you use a harmonic drive mount, such as The AM3: It would be very difficult to go back to any kind of normal (non-strain wave) mount!

The AM3 Harmonic Drive Mount from ZWO

The AM3 was just a pleasure to use; it’s the sort of situation where the equipment is  almost “out of the way”. It’s not a burden (like many other conventional mounts can be). It allows you to focus on other aspects of your astrophotography.

• Insure that the mount shows up in your list of Available Networks / Select it on your smartphone/or tablet (this also helps make faster connections in the future).
• Bring your mount/rig outside - Mine is always ready-to-go, with The AT80EDT refractor on it. I’m sure this is common practice (with small-medium sized refractors).
• Set-up rig: pointed North (polar alignment). Supply power/plug-in, power on.
• At this point, you should be able to launch The ZWO Mount software, and select an object to slew to. 

While we’re on the subject of polar alignment… Polar alignment with The AM3 harmonic drive mount is different than what you’re used to…

So, I might go as far as to say that: In the beginning, you might miss the original way of polar aligning (I did!).

When you’ve done something the same way for many, many years – it’s not easy to learn/get used to a new way of doing it. 

With The AM3 Mount:

• You make sure that your rig (mount & scope) are in the Home position - Not Park. *For those who aren’t aware, there’s a difference!
• Then, you point your scope to your respective polar alignment position. For those of us in The Northern hemisphere, that is the NCP / near Polaris (“the North Star).

*Home Position, is the position in which you would point/align your telescope to the North celestial pole (for those of us living in the northern hemisphere). The South celestial “pole” / area for those in the southern hemisphere, to put it in simple terms. 

The “Park” position, was/is designed for use in an observatory. Those operating inside any type of observatory, would utilize the Park position, to keep the telescope out of the way, when opening/closing the dome.

I know, pretty neat, right? 

Everything is, of course well-covered, and illustrated in the (freely downloadable) user manual. 

However, I will mention page 16 of the user manual; and draw your attention for a moment, to figure 3.4.1 entitled ‘How to adjust the latitude?’

Why this particular figure? Because the number 341 is some kind of lucky number for me, so there you go – maybe it’ll bring me some luck if I mention it in this review?

Some additional (selected) Specs:

• Uses Strain wave gear + Synchronous belt technology; with a reduction ratio of 300:1
• Typical periodic error of only +/- 15"
• Latitude adjustment range: 0 to 90°
• Maximum slew speed of 6° per second (pretty fast in use).
• Mount can operate down to -40° Celsius 

There are two gears, to adjust the latitude on The AM3 Mount. This is done using the included M6 Allen key – by loosening two hex screws (counter-clockwise).

Gear 1: goes from 0° to 60°. 

Gear 2 goes from 30° to 90°. Again, it is all well covered, and illustrated in the (downloadable) user manual.

Switching The AM3 Mount from Equatorial mode to Alt–Azimuth mode, is done via the hand controller. You press and hold the ‘C’ (cancel) button, while turning on The AM3 Mount’s power button. When you release the ‘C’ / cancel button, the status indicator light turns to green, from red.

...Currently “migrated” to DSLR-based AP

Upon deployment, on subsequent nights, you’ll most likely just need to make a mild adjustment (to get accurate polar alignment).
Luckily, the overall accuracy of the mount helps matters.

Pros:

• Lightweight, easy to move around/re-position.
• Able to hold large telescopes, without much concern about balance/balancing, etc.
• Robust, accurate, and fairly quiet.
• Ability to function in equatorial, as well as Alt/Azimuth mode!
• Boasts many features, including: WiFi, Bluetooth, and (wired) hand controller.
• Operates seamlessly with just about all astrophotography software out there.

Cons:

• Relatively expensive, compared to several (conventional) mounts out there.
• The TC40 Tripod (which suits it best) may be considered a little expensive (although it can be found for as low as $349 at Astronomics).
• Polar aligning will take some getting used to…

During my test period: I have used The AM3 Harmonic drive Mount in a number of different ways:

• The conventional way: Using more than one model of refractor telescope for astrophotography (as seen in photos above).
• Using both dedicated Astro camera (CMOS) and DSLRs.
• With just a DSLR and telephoto lens.
• As an Alt/Azimuth Mode mount: For both telescope, and binocular visual observing!

Just to give you an idea.

These are very low cost Barska brand binoculars (15x70)

I hope to get a chance, to try a nice sized binocular telescope on this mount – personally, I think it would be a lot of fun!

I also enjoyed attaching my Canon DSLR and lens directly to this AM3 Mount, with great results (still post processing)…

The AM3 is obviously a versatile tracking mount, for more than just astrophotography - Although admittedly, I’m probably one of the few people who’ve actually used it for visual observing! Yes, it may seem a bit odd…but it is nice to know it can do it.

Aside from doing your polar alignment in a new, different way…The only obvious, and real “obstacle” I can see, is the slightly higher cost.

There are many astrophotographers, trying to accomplish some good astrophotography, while staying within a reasonable budget. For folks like us, the expense poses a bit of an obstacle. 

However, I could not see anyone spending the same amount of money on a non-strain wave mount.

As for a few specific examples, take the top end mounts from Sky-Watcher…

Equatorial, GoTo mounts, such as:

The HEQ5

The EQ6-R Pro

The AZ-EQ6 Pro 

The bottom line, is that The ZWO AM3 Harmonic drive equatorial mount can be found for as low as $1499 US dollars at Astronomics.

So - this would be my recommendation (which, for many, will seem like a “no-brainer”) - if the Go To mount which you are considering, costs as much as (or more than) The ZWO AM3, I would advise you to go for The AM3. 

However, let’s not forget the tripod. If you don’t have a suitable/sturdy enough tripod - you’re obviously going to need one. 

You may find yourself leaning towards getting the TC40 Tripod from ZWO – because, of course, it fits the AM3 mount like a glove. They were basically made for each other. So you must take into account the expense of ZWO TC40 tripod, when considering the total cost of your mount.

In the spirit of not overlooking anything or leaving anything out: I’d like to mention, that for those who don’t mind spending a bit of money on an extra gadget - which will make your life easier - I would like mention The PoleMaster made by QHY. You can read about it, and see about ordering one, by visiting Explore Scientific (for starters).

The PoleMaster is a fascinating little gadget, which mounts onto the front of your telescope mount, and allows you to accurately (and easily) polar align. I have not used one myself, but it seems to be an ideal addition to an AM3 Mount.

I will add any additional items of interest to this review, as needed.

A huge thank you, to ZWO for the loan of the equipment for this review!

Next up, will be a review of The Astrophotography Manual A Practical and Scientific Approach to Deep Sky Imaging by Chris Woodhouse. This is the very latest, second edition. I can tell you right now, if you enjoy using dedicated Astro cams (CMOS) for your Astrophotography – then you simply must get this book ASAP!

Until next time,

Clear skies!

Review: The AM3 Harmonic Drive Mount and TC40 Tripod from ZWO - Part 1 of 2

Review: The AM3 Harmonic Drive Mount and TC40 Tripod from ZWO - Part 1 of 2

The AM3 Harmonic Drive Mount from ZWO is a Strain Wave drive telescope mount.

Photo credit ZWO / Stock photo.

If you haven't seen it already, you should have a look at my 'Arrival and First Impressions' post.

Additional benefits of The Strain Wave Drive technology:

• You no longer need to even balance your telescope! This is great!
• There aren't any clutches to tighten or loosen, lock or unlock, etc.
• It is accurate! Strain Wave mounts experience very little periodic error (ZWO guarantees less than +/- 20 arcseconds (this is low enough to have no noticeable effect on your imaging).
• It may function in both Equatorial and Alt/Azimuth mode. 
• In addition, each AM3 and AM5 comes with a certificate, stating the (individual) mount's amount of periodic error - Awesome.

Unboxed and set-up - On The TC40 carbon fiber tripod by ZWO:

The AM3 comes provided with a sturdy, styrofoam-like box (similar to what The Seestar S50 comes with). Also included in the box:

• The AM3 Mount
• A 2-meter long, angled, gold-plated USB cable.
• The unique PEC test report.
• A Quick Start Guide (Instruction Manual).
• The Hand Controller & Hand Controller cable (coiled, 2 meters long).
• 2 appropriately sized allen key wrenches (M6, and M4, for mount adjustments).

The AM3 can carry 17.5 lbs of equipment without a counterweight. If and when the need for heavier rigs comes up - Installing the optional counterweight bar & counterweight, allows The AM3 to hold 28.5 lbs of equipment!

All from a small, lightweight mount, which itself weighs only 17.5 lbs!

It features:

• A strong load capacity of: 8kg- Without a counterweight - and 13kg with a counterweight installed.
• It can function as an equatorial mount -Or- As an Alt-Azimuth mount!
• It uses Strain Wave gear technology along with a synchronous belt system.
• The AM3 (and AM5) utilize a compact and lightweight design.
• The mount is provided with a hand controller, as well as WiFi, Bluetooth, and built-in Live Star Database.
• It is ASCOM compatible (of course), and may be recognized as a (Meade) LX200 (by older software systems).

Following up on this last bullet point: I have tested The AM3 mount with a plethora of currently available software - And I have yet to find a software application which doesn't instantly recognize, and work with it!

At the most basic level, The AM3/AM5 mounts may be controlled by the ASI Mount App (both iOS & Android) freely provided by ZWO. I like the fact that firmware updates are automatically prompted.

At first, I found it quite amazing, that such an advanced piece of equipment could be easily controlled via a smartphone.

Sharing some screenshots from the easy set-up process

beginning with the installation of standard ASCOM software/drivers:

Where you get the ASCOM software

Selecting/Installing (defaults) ASCOM software

When ASCOM Platform has been installed successfully, you'll see this:

The AM3 mount has a dual saddle; which means it can hold either a:

Vixen / V-Style -or- a Losmandy / D-style dovetail.

While testing the mount, I also checked out how it would work for visual astronomy. I first tried the mount in Equatorial mode. It took a little getting used to: remembering the directions in which the scope moves, in relation to the movement of the joystick. 

Afterwards, I switched it to Altitude/Azimuth mode, and it worked much better! Much easier to get comfortable with it's movements. This mount can serve many functions. The indicator on the mount lights-up green to indicated Alt/Az Mode (Red for Eq Mode).

Initializing Auto/Online Update for the AM3 Mount:

The AM3 Mount is automatically updating itself - Very convenient!

I was running N.I.N.A. at the time...

The AM3 Mount successfully updated it's firmware - Neat!

Yes - That's N.I.N.A.

The AM3 Harmonic Drive Mount may be ordered directly from The ZWO Site. 

If you live in The US, Astronomics carries the full line of ZWO Mounts and accessories. 

Additional features include:

• LED status indicator (bi-color) to inform you of the Mount's current role (Eq. or AltAz.), as well as any error conditions. As does the lighted Power-on button.
• USB port - A USB 2.0 port - For connecting to an ASIAIR, etc.
• Auto Guide port / Guiding port (ST4 cable).
• Hand controller port - This features a rocker-style joystick, which may be moved 8 directions.
• 12v DC power supply port.

Please note: The mount isn't provided with a power supply/plug. You can order the ZWO 12V 5A AC to DC Adapter, at time of purchase. ZWO manufactures Pier Extensions to be used by folks with much larger refractor telescopes. ZWO makes both 160mm (6.3") -and- 200mm (7.9") Extension Piers as available options for The AM5.

And, of course, the ZWO TC40 Tripod is perfectly matched to the AM3/AM5 Mounts.

At this point, I would urge you to visit ZWO's Page on The AM3 Mount, to see all of the technical features and specifications. There is even a Special WO RedCat Edition of the mount - A result of a joint project with Williams Optics - (another outstanding manufacturer of astronomy equipment). It's a Limited Edition, with only 35 units being made!

The AM3/AM5 mounts are very unique! They definitely take a bit of getting used to - The AM3 is unlike any telescope mount I've ever used. One of the main things you'll notice right away, is how easy it is to use. Once you begin using one of these mounts, it will be near impossible to want to use any other kind. Now, you'll have all this extra time available - from not having to adjust, and re-adjust the settings you would on a typical EQ mount.

All ready to go!

I've used The AM3 with all of the popular AP equipment control applications out there today. Including: N.I.N.A., APT, PHD2, etc.

As well as planetarium software, such as: Cartes du Ciel, Sky Safari Pro, and more! And it just always works! 

In addition to the TC40 carbon fiber tripod, which Astronomics happens to have a great price on; there are several additional accessories available - Which include:

ZWO Counterweight Bar, and ZWO Pier Extension for The AM5.

Note: I am not affiliate with Astronomics either, I just noticed that they offered ZWO products at good prices.

All ASCOM Components updated:

The AM3 (and AM5) Harmonic Drive Mounts from ZWO, are the kind of mount one would buy, when you simply want your equipment to work - and work well. If you are tired of mucking about with the "conventional" types of equatorial mounts: Loosening, and tightening clutches, spending time balancing everything (esp. if changing telescopes), having to carry/move an awkwardly shaped (and heavy) mount around - Then you should be looking into an AM3 mount.

And yes, you will pay a bit more for an AM3 Mount...But a Chinese adage comes to mind: "Cheap things are not good, good things are not cheap"

Stay tuned for Part 2 of 2 of The AM3 Mount review coming up...

Thanks again, and Clear skies!
