Honest and Unbiased Reviews of Astrophotography Equipment Part 1

First, Smart Telescopes - My thoughts and experiences: Simple, not-too-technical explanations, of the (affordable) Smart Telescopes: The Dwarf 2 and The Seestar S50. I've been using The Seestar S50 a lot more lately.

Have you taken a good look at some of the images captured with the Seestar S50 lately? You can always go to the Seestar S50 Official Group on Facebook, and just have a look. What you see, generally, are average people acquiring some phenomenal photos of deep sky objects - using just a Seestar S50. 

Of course, there are some “outliers” who put in some extra effort, and a lot of extra time – and achieve really remarkable results. Probably the most amazing part of it, and this is coming from a bona fide astrophotographer, is that when compared to images acquired using conventional rigs: the results from the Seestar S50 are commonly as good, and often better, than those acquired while spending a lot more money (and time). 
I have spent a lot of my free time recently, simultaneously, adding components to the conventional astrophotography rig I have; testing it, etc. 
I've also been researching all of the different results which other hobbyists have been getting, using different combinations of equipment. Astrobin.com is a great resource, For doing some quick and easy searches – to see images acquired with specific equipment. 
Of course, I’ve been looking up equipment similar to the rig I currently have, as well as possible combinations of scopes and cameras, which I’ve considered upgrading to.

There are almost a dozen different scope / camera combinations I've considered: From Newtonian astrographs, to 6" SCTs, even considered the "exotic" (lol) Ritchey Chretien!  
And many cameras, from DSLRs to CMOS... And I could hardly find any (modestly-priced) combination, which would produce substantially better results than my Seestar S50. 
The only (affordable) scope I came across, which would show a noticeable improvement in overall image(s) were the popular 6" F/4 Newtonian astrographs (like this one - for one example). Or this one, which is at least in stock.

This is my current set up: 

How it started...

How it progressed...

How it ended up...
(still in progress)


Software, which is being tested extensively is:
These are all very good, but for now the ones I’ve settled on are:

APT
 &

I like using APT because it gives you real time feedback on everything that’s taking place: There’s live view, you can look at your actual sub frames, you can see the battery status of connected equipment, etc. 
I just find it all intuitive and very easy to use. I may also be a bit biased, because it’s the software I’ve used in years past.
I purchased a license for Sharpcap software; I’m looking forward to trying it’s live stacking feature.

Among the DSLR combinations I was looking into, were the following: 

Canon 550D + 80/90/102mm refractors 
Canon 5D Mk II (inspired by Astrobiscuit!)
Canon 60Da (inspired by Trevor Jones – Astrobackyard)

Nikon D5300 (inspired by Nico Carver – Nebulaphotos)
       &
Canon SL2

Canon T7i
       &
Nikon D5600 (inspired by Jerry Lodriguss – Astropix).

Other cameras by Canon which I’ve been looking into:

6D MkI
6D Mk II (full frame sensor)
5D MII
5D Mk III
450D (because of how inexpensive and versatile it is).

Other cameras by Nikon which I’ve been looking into:

D7500
D5500
D850
D810A (full frame sensor)
D600 (full frame sensor)
D700 (full frame sensor)

Until next time,

Clear skies!

Story #2 - Being Disabled and The Convenience Of Smart Telescopes

I was on the fence for quite a while, about whether or not to discuss this subject on (any of) my blogs. 

So, I've decided to go ahead and post my little story here ('Story #2') on my Astronomy Blog. This topic coincides with the wonderful convenience which the "new" smart telescopes provide.

I've made some new (online) friends over this past year: Both in the world of Bat Research, and Amateur Astronomy. So, as an 'FYI' for them, and as a way to illustrate the usefulness of smart telescopes...

There are 1 billion people, 15% of the world's population, disabled today. At the age of only 39 - I would've never expected to have my career come to a halt. I wouldn't have expected it in million years.

In an effort to make a long story short: I found myself coming home from work, not just tired (like everyone else), but with increasing levels of back pain, and body-wide inflammation. When it got to the point where normal movement became difficult, I consulted Doctors.

It's interesting to note: The first couple of Doctors I visited (General Practitioners), attributed these issues as being: "muscle related", "possibly arthritis", or other run-of-the-mill issues.

The third Doctor I visited (a Pain Management Specialist), sent me for X-Rays & MRI's. It was discovered that I had 8 damaged spinal discs: 4 in the mid-back; surgery not an option (due to proximity to thoracic region). 3 discs in lower back (Lumbar region) surgery not an option there, as a perfectly healthy disc would be affected. As well as 1 slightly damaged disc in the neck (cervical region).

I was also diagnosed with Fibromyalgia; by more than one Rheumatoid Specialist. In the years which followed, I had many tests done, and several medical procedures. I'm not going to go off on a tangent here, or get into all the details, etc. - The main points I'd like to make are that living with chronic pain & fibromyalgia (and most recently, diabetes) isn't easy.

The majority of my time is spent in bed. I never know when I'm going to feel okay; which makes planning to enjoy astronomy, or astrophotography (on clear nights) close to impossible. 

I was involved with both the visual, and AP facets of amatuer astronomy, since I was a freshman in high school. For about the past decade, trying to enjoy astrophotography was very difficult. There were quite a few steps involved in the set-up of the equipment, for a night of imaging. 

As you might imagine, there were many nights when the sky conditions were excellent - and I simply couldn't manage to set anything up. To say it was frustrating, would be a gross understatement.

With the development of these compact, smart telescopes - I've found that this is no longer the case. These new smart telescopes for astrophotography are practically effortless to set-up. The Seestar S50, for example - can simply be placed on a flat surface outside, and powered on. Then, you can just go back into your home, and control everything via smartphone or tablet. The Dwarf 2 is amazing - and almost as easy to set-up: You simply need to let it go through it's calibration process (successfully) and then you can also go indoors!

People sometimes like to say that the Dwarf II's lens is too small...But, have you ever seen what some (dedicated) astronomers accomplish with cell phone cams??

Anyway, this is a real game changer for just about anyone with disabilities. Which is really amazing, and is the reason why I'm sharing all of this.

For the first time in about 15 years, I won't have to miss out on any clear nights! I'll be able to just go out on the deck, and place a smart telescope on an outdoor table (or other flat/sturdy surface) and that's it! The rest is smooth sailing...

Well, that's my short post (for now). I'm happy to report, that:

  • The 2-Part Review of The Dwarf 2 has been posted here (Pt.1 - Pt.2).
  • The Seestar S50 review will be posted here soon!
  • And, last...but certainly not least: Instead of my (usual) live webinar/presentation on the lastest bat detector, I'll be talking about these two new smart telescopes! As well as the hobby of amatuer astronomy! For the members of The BatAbility Club (based in Scotland).

Stay tuned - More interesting stuff coming soon!

I just got a new telescope today! So, I'll be reporting on it - All I'll say for now, is that it's the first GoTo telescope I've ever bought... I want to especially share what it's like, having a new "conventional" telescope next to a smart telescope...

Also: A few of you may remember me posting about some beautiful vintage telescopes a while back? ...Well, they may yet find their way here! We'll see...

Looking forward to it!

Clear skies!

Sharing Some Stories - Story #1 - How I First Became Interested In Astronomy

How I First Became Interested In Astronomy 

When I was in my first year of high school, I came home one day, to find that one of my older brothers (John) had a new telescope sent to me.

Of course, as you might’ve guessed it was the ubiquitous 60mm refractor!

I was very excited, but at that age, with no experience with astronomy, and no one around to guide me, I didn’t really know how to get the most out of it.

And although I lived under Bortle 4 skies at that time, all I ever managed to do with it, was to look at the moon and planets – I think back now, and think to myself: what a waste of dark skies! That was what first sparked my interest in astronomy.

Through the years since then, I’ve always had a telescope of one kind or another around. I really became immersed in astronomy, and at one point even invested in more than one pair of Fujinon binoculars, along with matching nebula filters, a TeleVue telescope (The Pronto), as well as a new 8 inch Dobsonian. But it was all still visual astronomy.

Discovering Astrophotography

As it so happens, to many of us amateur visual astronomers, we eventually become interested in astrophotography; and I was no different.

As for my career, I was an Information Technology Professional, working for many fortune 500 companies, in fast-paced New York City.

Nevertheless, when it came time for my hobbies, I was still on a limited budget. Astrophotography can be an expensive hobby; and I didn’t have a lot of discretionary funds available to spend on expensive equipment. So I looked into ways that I could enjoy astrophotography on a low budget.

My first forays into astrophotography, consisted of wooden barn door trackers with 12V stepper motors, and 35mm film cameras! I used many different models (mostly rangefinder types), and also used gas-hypered film! 

Gas-hypered film was offered by a company, called Lumicon, and I’m pretty sure I was the individual who purchased the very last rolls they had in stock. Gas-hypered film is no longer available anywhere…Something which in this day and age, would be considered an ancient relic! Well, in those days, gas-hypered film was made, so that amatuer astrophotographers could capture colourful nebulae with their film cameras.

My collection of (relatively low-cost) 35mm film cameras. I experimented with each of these for astrophotography.


At some point in the future, I'll scan some print photos I'd made with gas-hypered film, and add them to this post. For now, here is a Pic of one of my better barn door trackers:

Homemade barn door tracker (purchased from another hobbyist online). I provided ~10.8v DC power, in order to get 1 "tick"-per-second from the stepper motor. 


Making Progress In Astrophotography

Things slowly continued from there; I was able to acquire slightly better equipment, over time (but still always low budget!). I even experimented with a low cost (Meade) one shot color CCD camera, attached to a 135mm (Canon) lens.

M17 - This was taken with the Meade DSI CCD camera, attached to a canon 135mm F/2.5 lens, set at F/4. A stack of 87, 2.8 second exposures. Stacked using Nebulosity‘s drizzle feature.
 

I eventually (finally!) progressed to a modified Canon DSLR camera, along with slightly better mounts. I can still remember how off-the-charts happy I was, when I got that used, Ha-modified Canon DSLR! I also bought an extra lens from the seller.

The astrophotography experiments continued; at this time I was living under Bortle 8 skies, (in Bronx NY) not too far from New York City.

As I advanced, the thing I began to notice, was how astrophotography required quite a bit of time in front of a computer screen - processing the images. As an IT Professional, I already spent almost 9 hours a day, looking at computer screens!

Believe it or not, this was one of the main reasons why I would take long breaks from the hobby. I simply didn’t want to spend so much time in front of a computer screen, stacking and post processing images.

NGC 1499 The California Nebula. This is one of my better images, taken with a modified Canon DSLR.

Discovering and using The Dwarf 2 

Then, just recently, I discovered The Dwarf II smart telescope from DwarfLabs.

When I first stumbled across the Dwarf 2 - It was like wow! I started seeing the images people were taking with the Dwarf 2 – and they looked great!

So I immediately decided that I simply had to have one!

I’ve been using mine on every clear night, since I got it. Of course, there are many wonderful pros about owning and using a Dwarf 2 smart telescope. The characteristic I appreciate most, is how the images look so good – and that with just a little basic “cleaning up”, most often directly on your cell phone, they are ready to share with friends and family.

M31 - 150 sub exposures of 15” each. Taken and stacked by The Dwarf 2. 
Minor post processing.

There are many things that I like about The Dwarf 2, but 2 factors which are most prominent, are:

1. The way it’s like having a tiny robot, doing your astrophotography for you. I mean, it's out there in your backyard...sometimes, in the freezing cold, taking photos of deep space for you...It might as well be a Probe Droid 🤖

2. And, the wide fields of view it provides. It is able to comfortably frame many of the larger deep sky objects, where other smart telescopes cannot.

On these nights, whenever I leave The Dwarf 2 outside in the backyard, to do it’s imaging: I walk back into the house, with a big smile on my face, saying to myself: “I love this thing!”

In fact, as I type this, my Dwarf 2 is on my deck; taking (and stacking) images of NGC 6946 The Fireworks Galaxy and open star cluster NGC 6939 - Since they both fit comfortably in the field of view!

I'm looking forward to doing more astrophotography with The Dwarf 2!

Keep an eye out for Story #2, coming soon...Until next time,

Clear & steady skies to you!

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

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...

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!

Thoughts On The Dwarf II Smart Telescope From DwarfLabs Part 2 of 2

Thoughts On The Dwarf II Smart Telescope From DwarfLabs Part 2 of 2

Continued from Part 1 of 2.

First and foremost: It's here!! Yay! The Dwarf II arrived today (directly from DwarfLabs in China). Now, I usually "save" all the unboxing Pics for the actual review post...but, I'll share a couple:

😁

Box delivered by DHL - Pen shown for scale

Unboxing The Dwarf II


Let’s consider the realities of Astrophotography. We should really be thinking about, or more specifically remembering our early attempts: those which many of us have made, to capture Astrophotos in the past.

People who enjoy amateur astronomy, almost inevitably begin to get interested in astrophotography...At some point! The first steps (some of the first attempts) are what some of us usually try.

The equipment and things we first experiment with, when we first try to capture images of the Deep Space Objects (DSO's) for example.

Typical first attempts include things like: 

  • Holding a cell phone camera up to the telescope (or binocular's) eyepiece.
  • Probably followed by using a cell phone holder attached to the eyepiece of the telescope, or pair of binoculars.
  • Holding a point & shoot digital camera up to the eyepiece.
Note: Only very short exposures are possible - Most likely, only one or two seconds; which, then makes it necessary to collect very large numbers of exposures to stack.
  •  You'll have slightly better success if using a scope on a tracking mount, but after a while, you'll probably become dissatisfied with the results.

Again, I suppose I'm of the opinion that anyone who has enjoyed astronomy for any modest length of time, has at least made some attempt at getting a picture of what they're seeing...

In traditional astrophotography, there is a lot of work involved for post processing your acquired images on a PC. 

I can't say that Adobe Photoshop is required; but it is highly recommended (and it's not cheap!) Luckily, there are a few free programs you can use nowadays - Gimp, and Siril come to mind; there are others too. Incidentally, I'm currently learning my way around Siril :) Why? because most owners of The Dwarf II are using it! It's actually a nice bit of software (more on that later).

Sometimes, you can end up spending money on additional, third-party software. I'm referring to the (small) software applications, sometimes even Plug-Ins, specifically designed to help astrophotographers. 

More often (these days), someone might go in the direction of using a standard or modified DSLR camera, and a tracking mount. I've done this several times myself, in fact! This solution isn't as expensive as the others; which some people get involved with, further down the road in the hobby. I'm referring to good quality refractors, mounts (GEM's, etc.), and cooled CCD cameras...but let's slow down here a minute! 

Main factors still consist of having to work to acquire dark frames, flat frames, bias frames, and finally light frames (actual image frames). These then need to be transferred to a PC (a seperate file folder for each). Followed by the preliminary stacking. After the first raw stacking/raw image stacking takes place, then comes:

  • Multi step process of manipulating (enhancing) the image commonly in Adobe Photoshop. 
  • After applying all of the basic modifications, to improve the overall image.
  • The next step is to apply the features of various third-party software, etc.
  • So, finally, after all of the image processing is complete you finally have an image that you’re somewhat happy with.

This entire process becomes even more involved, and more labor-intensive (post processing) when an amateur moves to a dedicated camera such as a (cooled) CCD.

With a small relatively inexpensive system like the Dwarf II - You get to eradicate many of these steps!

The Dwarf II is like a miraculous gift when it comes to astrophotography! It is especially going to be most appreciated by many of us who have already gone through the steps of getting into, and sometimes out of, the astrophotography hobby.

It simply makes everything much more pleasurable. It makes astrophotography much less frustrating. Also much less labor-intensive. As for me, the post processing of images was my least favorite part of astrophotography. Have you ever tried post processing astro images on a somewhat older (slower) laptop??

That can be very frustrating! (OK, painful!).

When using The Dwarf II, this issue is practically nonexistent. Post processing can be done on the smartphone itself! And done! Your pics are ready to be shared with your friends on social media!

Doing some simple post processing - practically just a few minutes worth of adjustments, right on your cell phone is typically enough to render pretty nice deep sky photographs! You can achieve very nice looking astrophotography images of DSO’s, with just a few minor adjustments - available right in The Dwarf II's software! On your smart phone!

Then the image can be uploaded straight to your social media accounts to share with friends! What could be better than this? 

Another point that comes to mind, is the difficulty of enjoying astrophotography during the Summer months: it’s hot, humid, uncomfortable...and there's lots of mosquitoes. In some places, the mosquitoes can be really awful, necessitating the use of bug spray all over yourself. And for those of us who have done astrophotography during the Summer months, we can attest to the uncomfortable, frustrating issues involved. Ugghh!

Something else to consider: I'd like to draw your attention to the early months of Autumn - Or should I say, the months between Summer and Autumn? When there are certain combinations of temperature and humidity, which causes lenses to fog up! The areas between your eye and the eyepiece also fog up. These are things that can make visual astronomy, and conventional/traditional astrophotography quite frustrating. 

The Dwarf II eliminates all of this, because you can simply leave it in position, and then go inside - While it continues to capture images for you! And what’s even more astounding, and perhaps could be described as miraculous: is that you can control everything, by simply using your smart phone! Now of course, I realize that some of the conventional (expensive) rigs allow you to do this too. However, it can be said in a nutshell, that for under $500 US (or under $600 US for The Deluxe version), you can have a tiny little observatory - Which can be controlled remotely from inside your home! If you have a window facing The Dwarf II (WiFi/control range is ~15 feet).

What this translates into is: You can now do all of the astrphotography that you’ve been wanting to do (your Summer constellations & DSO's) without having to endure all of the drawbacks, the sweating and humidity, and mosquitoes! 

So again, The Dwarf II comes to the rescue by being a unit which doesn’t have to have your face placed against it - Causing: Fogging, condensation, humidity buildup, etc... Once again, it’s a matter of setting The Dwarf II on the tripod provided, or tripod of your choice - and completing some very easy steps.


A sneak peek at some unboxing Pics!

Doing the initial turning on, acquiring just some 'Astro Darks' (dark frames) and once again, either controlling it from a short distance, or even controlling it from inside your home (if you have a window facing the Dwarf II's position). 

Another point I’d like to bring up: I happen to be one of those people who didn’t mind cold temperatures.

Many years ago, I was able to tolerate cold temperatures with no problem. But now that I’m older, the cold seems to bother me a little bit more. Once again, The Dwarf II comes to the rescue – because once again, the set up is so easy and quick! Once the unit is set up outside, and the preliminary set up and positioning is done: You can then retreat inside, to the warmth of your home, to finish controlling it via your smart phone. 

These basic capabilities, these basic ways of operation of The Dwarf II, simply make it a no-brainer, when considering whether or not to get one!

It may be small, but there’s no reason for it to have to be large. The fact that it’s so small, has a lot to recommend it. There are lots of great advantages to the fact that it's such a tiny unit. It allows you to place it in an endless choice of locations. I only had it outside for 10 minutes (during the day) today. And there were many places where I could place it, where I would never be able to put a conventional DSLR, etc.

One of the things that need not be a concern is your smart phone's battery running low, since you can plug in your smart phone. You can charge the battery while you’re still controlling The Dwarf II.

This is also a great convenience! A final thought, for now: With The Dwarf II - you don't need to spend so much time sitting in front of a laptop to post-process your images. This is one of my favorite advantages. I was getting a bit tired of all the post processing steps. With DSLR-based AP: I was especially tired of all that time spent in from of the laptop screen. That's one of the big reasons why I welcome The Dwarf II! I can say goodbye to all that stacking and post processing! 

The images look good enough, where they don't need it! The Dwarf II does the stacking for you - and all you typically need to do, is a little bit of basic "post processing" and viola!

You have astrophotos ready to be shared with your friends!

I'm looking forward to comparing the astrophotos I took with my $1000+ set-up, against the ones I'm going to take with The Dwarf II! I'll be imaging the same Messier objects!

Much, much more to come, stay tuned!

The Dwarf II - An Awesome New Product!

I want to bring your attention to a smart telescope, which was released earlier this year (2023). It is The Dwarf II automated photography system, and as you’ll see: it's a miraculous device!

The Dwarf II on it’s included tripod (stock photo).

It allows you to:

  • Create astrophotos of Deep Sky Objects - Pretty much automatically!
  • Focus on, and take photos of terrestrial animals.
  • Create sharp, panoramic photos of landscapes - With just a few clicks!
I’m very happy to inform you, that I will be posting a full, multi-part review of The Dwarf II soon…
So, while writing this first, "online look" at The Dwarf II: A random question/idea just occurred to me - Who, exactly would appreciate The Dwarf II the most
Well, that's easy: Folks who have previously dabbled in (low-cost) astrophotography.
We are the ones who will appreciate this unit the most.
Why?
Because we have already gone through many attempts at astrophotography, while staying under a modest budget.

The many objects you can photograph with 
The Dwarf II (stock image).

It’s definitely the perfect device for those wanting to learn about astrophotography. It allows the user to be involved in the process-which is very much like traditional astrophotography. This allows the user to enjoy learning about the subject, and the process - which gives a feeling of accomplishment.

In an upcoming post, I can use myself, as an excellent example - I will share the equipment I acquired, and the resulting astrophotos (of DSO's) I was able to manage. 
This will give a baseline idea, of what it’s like, trying to do astrophotography on a budget.
Among the equipment which I will be discussing, will be:

1. Cameras on tripods.
2. CCD camera attached to Canon Camera lens, on an Orion motorized mount.
3. Modified DSLR, with Light Pollution filter(s) on various tracking devices.

Much more to follow - Stay tuned!

Clear skies!
