Review of The Dwarf II Smart Telescope Part 2 of 2

Review of The Dwarf II Smart Telescope - Part 2 of 2 

A very short un-boxing video

Right from the start, let me just "blurt out" some thoughts, from the top of my head: 

I've had this Dwarf 2 for about 2 months now, and even though there have been more clouds & rain than clear nights - Every time I leave it out there, to do it's imaging: I head inside the house, thinking to myself "I love that thing!"

It is amazing! That's why I (thought of) and shared this video on one of The Dwarf 2's Facebook groups:

Again, it really comes down to - Me having been into astrophotography for years; and now having a smart telescope:

• It takes under 5 minutes to set-up!
• It has GoTo ability - Which means it can find, and track any DSO you want!
• It automatically produces results, which in many cases, are even better than my DSLR set-up used to!

What's there not to like??

• The images, look great as-is, straight out of the Dwarf 2 (right off of the memory card).
• If you do just a little bit of post processing, right on your smartphone's default photo app: The images look fabulous!
• You can then share them wherever you'd like - Super easy!

For me, personally: I seriously dislike spending all of that time in front of a laptop screen - when doing normal (conventional) astrophotography. Having to do all of the arranging in file folders, and (necessary) stacking, etc., etc. 

As a former Computer Engineer, I used to spend all day at work, looking at computer screens...do you think I wanted to spend any more time looking at a computer? (in order to enjoy my astrophotography hobby)?

No way! I want to avoid it as much as possible.

Okay. What about the expense?

Yes, astrophotography is (and always has been) an expensive hobby. The Dwarf II is currently priced at $459 for the standard version; and $595 for the Deluxe version - You can just get a modified DSLR camera for about that much...and you still would need to buy:

• A lens of 135mm FL (or longer) -or- a telescope.
• A (good) tracking mount.
• A sturdy tripod.

This quickly brings you into the realm of about $1500+!

An image produced with my Dwarf II - The Eastern Veil Nebula

341 images of 15" each, taken & stacked by The Dwarf II; cropped and post processed in PixInsight software.

 

M20 - The Trifid Nebula. 153 individual shots of 15" each, taken & stacked by The Dwarf II. Cropped and post processed with Siril and Gimp (both free applications!).

When I first started astrophotography, I also experimented with film cameras! I even used (the increasingly rare) gas-hypered film - Which was only offered by a company called Lumicon. I believe I purchased the last rolls of that 35mm film in existence. 

And mounts as primitive as homemade (wooden) barn door trackers! These used simple gears, a not-so-simple curved bolt, and 12v powered stepper motors.

For those of you who have never done astrophotography - What you need to keep in mind, are all of the procedures and steps, which are required for traditional astrophotography - And that they simply don't exist when using The Dwarf II! 

The more thought I give to this subject in particular, the more I feel I could write about it. And, I wouldn't want to make this review too "drawn-out". Or, longer than it needs to be! It bears repeating at this point: Those who will appreciate The Dwarf II the most, are those who have done some conventional astrophotography in the past.

I couldn't resist showing a photo I managed; several years ago - Using a Ha (Hydrogen-Alpha) modified Canon DSLR:

An image taken with (conventional equipment) - Hydrogen Alpha modified Canon T3i DSLR, Clip-in light pollution filter, on a wooden barn door tracking mount. Shown here is The Heart & Soul Nebulae, as well as The Double Cluster in Perseus. Bortle 4 skies.

In operation, The Dwarf II is very easy to set-up and use; and more importantly, it is an accurate device. It's calibration sequence is automatic, and completes quickly. When you ask it to goto an object (from the Auto Goto List) it always centers the DSO in the center of frame.

In the past, while using conventional astrophotography gear: If there was a clear night, and I wasn't feeling well - that was it. I had to deal with the disappointment of not getting any astro-imaging done. With a smart telescope like The Dwarf 2, you only need to pop outside for a few minutes for set-up. Then you can go back indoors, and be comfortable while the tiny Dwarf II capture and stacks the images for you. You also get to watch it's progress, from your smartphone or tablet's screen - Excellent!

This is M8 - The Lagoon Nebula. A stack of only 37 frames! of 15" each, stacked by The Dwarf 2. Cropped and post processed using PixInsight.

Pros:

• Super small, lightweight, easy to transport anywhere.
• Additional (optional) batteries are available for purchase - which can be a great convenience.
• Ability to purchase & use third-party nebula filters, providing excellent results (especially in light-polluted areas).
• Offers a wide-field of view, required for larger DSO's.
• Offers good control over manual focus, which stays in place once set.
• Single exposures taken by the Dwarf 2 are made accessible by default, if user would like to stack them manually.
• Acquired images are written to an accessible MicroSD card, convenient for post-processing (on PC).

Cons:

• The list of goto/DSO objects (to automatically goto) is currently rather short.
• Imaging the same object for long periods of time, will begin to show the effects of field rotation (if The Dwarf 2 isn't polar aligned).
• Not ideal for smaller nebulae (such as planetary nebulae).
• Battery life could use improvement.

The Dwarf II may be ordered directly from DwarfLabs. Several Dealers of astronomy products also have them in stock/currently available for order.

NGC 281 The Pacman Nebula - A stack of 63 frames, 15" each, taken by The Dwarf II. Cropped, and processed in PixInsight.

Until next time,

Wishing you clear & steady skies!

Review Of The Dwarf II Smart Telescope From DwarfLabs Part 1 of 2

OK! So, I'll be doing a live webinar (presentation/review) on The Dwarf II smart telescope -and- Astronomy in general, for The BatAbility Club! On December 11th!
This is really unique and amazing! I'll be doing my best to present Dwarf II astrophotography to the club members; who are all experienced bat and/or wildlife professionals.

As always, it will be viewable to Club Members only. However, if you know anything about how thorough my reviews are...And you wanted to see an in-depth review of The Dwarf II - You might consider becoming a Member!

The lofty goal I've set for myself, is not only to introduce astrophotography to bat research professionals...but, to see if I can introduce astronomy hobbyists to the hobby of bat detecting!  

In any case, here is Part 1 of 2, of the full 2-part Review of The Dwarf 2 

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 an entire family may enjoy.

Dwarf II in it's box

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 (they are fully automated). 

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 focal length refractor

• Utilizing a Sony IMX415 sensor chip

The Dwarf 2 being unpacked (Deluxe Package)

The unit itself consists of a unique, super-compact design - It isn't much larger than a typical hardcover novel. 

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.

Generally speaking - The steps for using it for astrophotography are as follows:

• Attach the included tripod.
• Set it down outside.
• Turn the lens unit upwards (bet. 30 and 90 degrees).
• Click Auto focus (which will focus the stars).
• Choose Calibrate...
• Then choose the DSO you'd like to image.
• Check a few basic settings, and click the red button.
• You are now doing astrophotography!

The Dwarf II and all accessories fit nicely in carry bag.

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? 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!

*Lights are the actual photos (frames) of the object you're imaging.

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.

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.

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. 

A useful tip: I use this digital thermometer to check that The Dwarf 2 has cooled down (close to the outdoor temp.) before taking 'Astro Darks' (automatic Darks).

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.

The Dwarf 2 smart telescope - In it's carry bag - Ready to go anywhere!

For my part, I have purchased an excellent nebula filter...And it has provided a very noticeable improvement in my images of deep sky objects (especially nebulae). What I'm actually referring to is called a Duo Band filter. The one I bought, from High Point Scientific, is manufactured by ZWO:

The ZWO Duo Band nebula enhancing filter.

Part 2 of 2 is coming up next... 

Until next time,
Clear skies!

What Do You Know About Bats?

Many people have been led to believe, conditioned, or taught that bats should be feared. There is absolutely NO reason to fear bats!

When you take just a little bit of time, to learn about them - You will find, that bats are amazing, gentle, beneficial, long-lived creatures that are super cute as well!

In December, I'll be introducing Astronomy & Astrophotography to my 'Bat Friends!' I'll be using The Dwarf II smart telescope for the Astrophotography part.

So, at the same time, I'd like to present Bats to my Astronomy Friends!
More posts to follow...But Bat Awareness Week is coming up this month.
Consider getting yourself the cheapest bat detector (easy to build/no solder) kit on Amazon (I have no affiliation). There's this one made by Franzis also.

Neither one requires soldering, and they're super cheap!

Or any bat detector you'd like - If you've got more discretionary funds available - then, by all means get yourself a nicer one! And listen to the bats while you set-up your gear! ❤️🦇

Listen in on your local bats while you're observing! Or, on nights when it's a bit too cloudy to observe!

You may fall in love with bats (I have!) you may become fascinated with, and enjoy bat detecting! I happen to love bat detecting and bat detectors! You never know!

Here's my Bat Detector Review blog if you'd like to read the most in-depth reviews of bat detectors anywhere!

Well, in the meantime - I've been thoroughly enjoying frustration-free astrophotography, using The Dwarf II smart telescope!

Detailed review of The Dwarf II in progress...

Just Sharing Some Recent Images From The Dwarf II (for now)

Just Sharing Some Recent Images From my observatory Dwarf II!

There will be lots of images accompanying my upcoming review of The Dwarf 2 smart telescope...So, I thought I'd share a few now:

What can I say about The Dwarf II? This tiny device produces amazing results!

Affordable, smart telescopes, like The Dwarf 2 - Have changed the hobby of Astrophotography forever!

Galaxy M33 - Directly out of The Dwarf 2 - Zero Processing

The same image - With some processing in PixInsight

Please keep in mind: These images of DSO's, captured by The Dwarf 2, really don't require much post-processing. In other words, you certainly don't need to use expensive software like PixInsight. 

In my experience, some minor post-processing in free software Apps like: Paint.net, Gimp, and especially Siril - allow you to achieve excellent results! And, with less of a chance of "over-processing". Which it seems I may have been on the verge of doing, with the example above, of M33.

Also, the more time you dedicate to capturing images of each object, the better they'll look. The examples here, were very short duration sessions. None of them were much more that 100 images of 15 seconds each.

The following image of The North American Nebula, was accomplished with under 30 exposures:

The North American Nebula NGC 7000 - Straight out of The Dwarf 2 - Zero Processing.

Same image - With minor processing in PixInsight.

Some might be surprised to learn, that The Dwarf 2 was able to image a nebula as small as The Iris - Shown in previous post (below). But, this little unit continues to surprise me. 

The raw image of The Iris Nebula in particular, would benefit from some post-processing... It was taken with The ZWO Duo Band Filter attached. I bought my filter from High Point Scientific. I've ordered from them before, and they have great customer service. I bought my 10" Apertura Dobsonian from them, a couple of years back. And, this Duo Band Filter arrived very quickly.

Until next time,

Clear skies!

Some Images From The Dwarf II - Last Night!

Okay...of course, a full 2-part Review of The Dwarf 2 is coming... 

But, I couldn't resist showing some more comparison shots!

The Cocoon Nebula - 36 Min. total exposure time.

With The Dwarf II - 15" Exp. x 144, Gain:80, IR:Pass, 1.25" ZWO Duo Band filter.

Cropped, and only minor processing in Paint.net & Gimp.

Same for The Bubble Nebula

The Iris Nebula - About 30 to 50 minute exposure time.

The Dwarf II has changed the course of Astrophotography forever... I would never go back to a DSLR!

A GOTO scope with a CCD Camera...Maybe? I really like The Virtuoso GTi from SkyWatcher...

Until next time,

Clear skies!

Last Night, I Was Amazed By The Dwarf II Smart Telescope!

Astrophotography: Some of the things that come to my mind (things that I'm remembering) are the attempts which I (and I'm sure many other people) have tried in the past.

I used to use a DSLR, but before that - I experimented with film cameras, and a Meade Color CCD camera (the lowest cost unit they made). 

And here's an attempt at M31, many years ago, using a Meade color CCD camera attached to a Canon lens, on a cheap Orion tracking mount:

(under Bortle 8 skies)

M31 Beginner mistakes!

And here is an image from last night, under my Bortle 4 skies - about 150 15 second subs, stacked by The Dwarf II, with minor post processing in Paint.net:

I'm amazed by this little device! It used to take twice as much work, to get an image only half as nice!
