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!

Astrophotography: Conventional Methods Vs. Smart Telescopes - Must Read!

Okay, the first thing I need to tell you about me, is that I am crazy about hobbies.

I am very keen on hobbies in general, but when I get into a hobby, I go all the way. Not only in enjoying the hobby, but I also enjoy thoroughly researching all of the equipment, and accessories, which are used in the hobby.

And of course Astrophotography is no different; after getting (first) The Dwarf 2, and later the Seestar S50 Smart telescope: I was simultaneously researching standard/conventional equipment for Astrophotography. 

Working within the limited budget I have, my goal was to locate traditional Astrophphotography equipment, which would provide similar (hopefully slightly better) results, to those which were being produced by these smart telescopes. 

I would spend much of my free time, surfing the web and extensively researching: Which bundle, or combination of equipment, would give me the same (or slightly better) results...

Luckily, I have the experience (and skill) required to do conventional astrophotography. And I wouldn't mind putting in the effort & work, to do it "the old fashioned" way.

What I can tell you, is that it’s not really possible. 

I’ve tried for probably over two months. Again, spending whatever free time I had, trying to track down and put together, an inexpensive Astrophotography solution (starting from scratch, mind you) – which is to say, if someone were to go out, starting from zero – and buying the equipment required to do some simple Astrophotography. 

I also want to point out, that there are quite an assortment of “how to” videos, on YouTube, covering this topic. Which is to say, they have titles such as ‘How to do Astrophotography for under $2000’, or ‘How to do Astrophotography for under $1500’, and similar titles. I like the ones done by 'Nebula Photos' Channel (Nico Carver).

Yes, the aforementioned set ups (shown in those videos) would produce very good images of large/extended deep sky objects. But there are only so many large/extended deep sky objects to photograph… In the interest of full disclosure: I'm not one of those folks who enjoy large/extended nebulae that much...When I was doing DSLR-based astrophotography, those are the objects I was kind of limited to. I happen to really love planetary nebulae (which are generally small).

I began my research/experiment, with a budget of $1200, and quickly found, that I was unable to find any bit of kit to put together, which would even come close to the results produced by either of these inexpensive smart telescopes. 

I then raised my “imaginary budget” to $1500, and continued searching, surfing, and researching, for several weeks. I was still unable to find any equipment, which I could recommend to anyone for getting into Astrophotography. And certainly not to get into Astrophotography easily, without a rather steep learning curve. 

I simply couldn’t find anything which a complete beginner would be able to quickly or easily utilize. This was very enlightening to say the least. 

This is something that not too many people are speaking about. And by people, I mean the more well-known proponents/hobbyists/enthusiasts - And social media influencers involved in Astrophotography. 

So, the preceding paragraphs were simply a polite way to say, that these two smart telescopes have cornered the market on Astrophotography. During my research, I have seen and heard several stories, and read many posts from hobbyists - both beginner and intermediate/experienced Astrophotographers, stating their observations. Posts on social media, etc. to the effect of: “I have never been able to see deep sky object “XYZ” Using my 10 inch reflector before – yet this Dwarf 2 is able to see it and image it! 




I’ve come across quite a few similar statements, from different amateur astronomers/astrophotographers. I have read statements and seen photos, posts on social media, etc. (sometimes statements accompanied by photos) - where the hobbyist has been getting better images with either one, of these smart telescopes: Which turned out to be better in every way, when compared to the images they attempted to get, using their 8 inch Schmidt Cassegrain telescopes! 

Statements such as these, invariably cause you to pause and think for a moment.

It’s really astonishing, that anyone would admit (for lack of a better word) that $500 off-the-shelf smart telescopes, have been producing images which are not only as good, but (often) better, than their expensive telescopes & equipment have been able to produce. 

Now don’t get me wrong. Of course, there are many hobbyists who have good/expensive equipment, and:

  • Know very well how to get the best performance from it.
  • Know how to post-process images very well. 
  • Consistently produce images, which are easily/obviously better than the images from the smart telescopes. 

From what I've seen, in cases such as the above: The resulting photos tend to look noticeably sharper (for one thing!), have much more depth, and definition.

I recall a young lady who was using a very nice astrophotography rig, built around a good 4" apochromatic refractor. These scopes consistently produce some of the nicest, professional-looking images. And when she stated that one of these smart telescopes (The Seestar S50), was producing images just as nice as her rig... What??

I was simply at a loss for words. These are truly amazing findings. And I sometimes wonder, if these results are not shared more frequently, more commonly, and more widely for several other underlying reasons? Such as:

Perhaps some hobbyists would rather not disclose that a $500 smart telescope is able to take images as well as their $4000+ imaging set up? 

I sometimes wonder, if those who are very well known in the world of YouTube, as far as astrophotographers go, are reluctant to let this information be known? For fear of the negative impact it would have on sales of traditional (expensive) equipment for astrophotography?

As I typed this, I had the Seestar S50 outside on my deck, imaging NGC 1514 otherwise known as The Crystal Ball Nebula. It is a small planetary nebula, which for all intents and purposes, one would normally only attempt, using a good apochromatic refractor (or an 8" to 11" SCT!) along with a very steady & capable mount...along with an expensive, cooled astronomy camera…Yet, this Seestar S50 (a $500 smart telescope) has captured a very nice image of this object:


The Crystal Ball Nebula. Taken with The Seestar S50, a few nights ago. Only very minor post processing on my iPhone. A small planetary nebula, with only 18 minutes and 30 seconds worth of exposure time! And I think it’s very telling.

I’ve been doing my best to keep this concise, and not to go off on too many tangents. However, the other thing which I’m interested in pointing out, is that: 

I am among the hobbyists who would be happy, if conventional astrophotography equipment (along with the various skills required to manipulate images) was, in fact, still the de facto standard when it came to acquiring images of deep space objects. 

I'm happy to accept the idea that "if it were easy, everyone would be doing it".

I like the idea of something requiring a bit of study, and acquisition of a set of skills, in order to produce good results. 

And this goes for just about any hobby. Those I can think of, just off the top of my head: building scale models, building models from card stock/paper, tying full dress Atlantic salmon flys for display, hand carving songbirds from wood, etc. 

And on a related note, even creating pencil sketches of deep sky objects at the eyepiece. Using (typically a large) telescope, or sometimes even a pair of good-sized binoculars. However, almost any size instrument could be used.

These are all things which require one to develop skills, over time, in order to produce satisfactory results. And I like the idea of that. 

I wish I could say that the conventional methods of astrophotography give a very obvious/substantial improvement over the results from smart telescopes, but it seems I can’t. Not for ~ $2000…You’re going to have to invest quite a bit more if you plan to beat these smart telescopes!

For approximately a quarter of the cost required, to invest in traditional astrophotography equipment; you can get a device - Which practically does everything a set-up costing four times as much would do. And produces amazing results when it comes to the final astrophoto, obviously.

It goes without saying that this has revolutionized the way people enjoy astrophotography, and even astronomy to some degree. In the past, someone would have their conventional astrophotography set-up deployed in the backyard, whilst likely observing with another instrument (typically another telescope). These days, instead of the large, complex, time-consuming (to set up) traditional rig... A person can simply place a smart telescope outside, allow it to image, while they do some visual observing. And the “set up" of a smart telescope takes a tiny fraction of the time required to set up a traditional astrophotography rig. 

This obviously gives the user so much more time, to casually observe the objects in the heavens, which are of interest to them. For example, I intend to continue observing, visually, and even sketching deep sky objects; while my smart telescopes sit there and do their imaging for me. 

They are like little robots, doing all the work for you. Explained another way: I'll admit, that I am one of those people, who takes pride in having learned a skill. Having taken the time, and effort to learn new skills, which enable me to produce the desired results (whatever end results the hobby in question requires)... 

These two new, affordable, smart telescopes, have only been out for a relatively short time. So it’s still too early to make any concrete predictions.

However, as someone who admittedly enjoys doing things the old-fashioned way, the way which requires hard skills, I could not find any equipment to purchase with a budget of $2000+ which would produce better results than the smart telescopes, which cost only $500. 

And believe me when I tell you, I’ve tried, I’ve really tried! I'll admit, that I wish it were the case: that you could produce the same astrophotography results, with a budget of approximately $2000...But try as I might, I was unable to theoretically (or otherwise) prove it.  

These are the things, which, all of us as amateur astrophotographers, may end up brooding over a bit. We all still have free will, and we can still choose to do things the traditional way. However, in order to get results better than what these $500 smart telescopes can do – My guess is: We will have to invest somewhere between $3000 and $5000. I’m sure to some people, it’s worth doing that. Especially if they’d rather be able to say that: The work was done by them, manually, using skills that were acquired over a substantial amount of time. And that’s how the outstanding results were achieved. 

Unfortunately, for someone like me, on a low budget – able to only spend approximately $2000, I really can’t see myself producing images much better than what these smart telescopes can produce. 

Both of these telescopes have their strong points. They both have their pros and cons. I've reviewed each of them in detail, on my blog. Generally speaking: the Seestar S50 is excellent for imaging smaller, deep sky objects. The Dwarf 2 is essential for imaging large deep sky objects. 

Let’s keep in mind that the prices are very similar; at right around $500. 

Proving that I will “put my money where my mouth is" - I intend to try to "prove myself wrong" so to speak. And, I still intend to acquire some equipment – for around $2000, give or take a few hundred dollars. 

And I will put in the effort, to see if the proof is in the pudding. I want to see (with my own eyes) if this is indeed the case. So I plan to go forward with this experiment, and of course will be reporting my findings and all the relevant and interesting details.

So far, I've acquired a (lightly used) 80mm ED triplet refractor, a new ZWO ASI178MC, a ZWO Duo Band filter, and...I guess I'm making progress?

Until next time,

Clear & steady skies!

Review Of The Seestar S50 (Smart Telescope) by ZWO

The Seestar S50 is a smart astronomical telescope; more specifically a smart telescope, designed and manufactured by ZWO.

Incidentally, I'll be doing a live webinar (presentation/review) on The Seestar S50 and The Dwarf II smart telescope; as well as Astronomy in general, for The BatAbility Club! On December 11th!
This is really unique and marvelous! I'll be doing my best to present amatuer astronomy, and smart telescope astrophotography to the club members; who are all experienced bat and/or wildlife professionals.
As always, it will be viewable to Club Members only (you might consider becoming a Member!).

The telescope arrived (via FedEx in my case) and was well packaged & protected for it's long journey (from Mainland China).

This is where the FedEx delivery guy left the box for me – right next to the carbon fiber tripod I was using the night before 😀

The Seestar S50 weighs only 2.5kg, the tripod is only 0.65kg, and the carry case is 0.6kg.

The Seestar S50 can be ordered directly from ZWO, right from their webpage, dedicated to the Seestar S50. It may also be ordered from many different telescope dealers online - So you can try some of the places where you normally order your telescope/astronomy equipment from.

The Seestar S50 - Removing the product box from the shipping box.


The Seestar S50 shares many features with other smart telescopes, such as:
  • It's small and compact.
  • It's 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).
  • Comes with built in rechargeable battery. For comparison, The Dwarf II's (rechargeable) batteries are removable.
In the case of The Seestar S50 - The memory for storage of photos, is built in memory, of 64GB.

 
Additional technical specifications include:
  • A resolution of 2.1 Megapixels
  • Pixel size of 2.9um
  • A 50mm apochromatic lens aperture, @F/5
  • A 250mm focal length refractor
  • Utilizing a Sony IMX462 sensor chip


The Seestar S50 in its carry case.


The Seestar S50 sports a very slick design. It has a nice futuristic look to it, molded in black and dark gray. I find it very cool looking!



I am almost reluctant to describe how easy it is to use this smart telescope. Simply because sometimes, if something is very easy to use, it may not be taken as seriously as it should. Many people have a tendency to equate complexity, and difficulty of use, with something that is comprehensive and effective. 
So there’s a bit of a paradox here, the Seestar S50 is indeed very easy to use, however, the results it produces are very impressive:

NGC 7789  - Also known as Caroline‘s Rose named after Caroline Herschel (William Herschel‘s sister)

NGC 281 - Also known as the Pac-Man nebula.

NGC 2175 - The Monkey Head Nebula


I happen to like the blue Seestar banner on the bottom of the resulting photos. The Seestar S50's operating software is very advanced.

When it comes to who I would recommend this product for, the answer is: Anyone! Anyone, ranging in age from a (patient) teenager to someone of advanced age. Why?
Because operating the Seestar S50 couldn’t be any simpler – It only requires the main unit to be attached to the included tripod. The tripod legs opened, and the telescope placed on a flat, level surface. 
After which, you power the unit on - by holding and pressing the power button for a few seconds. The unit powers on with an audible beep, and the red and amber LEDs illuminate, indicating that the unit is powered on. 

The only section which may require a bit of dexterity (or "skill"), is the navigation of the Seestar software. This software is an astronomy/planetarium-like application. 

I may be going out on a limb here, but if a person already has an interest in astronomy, there’s a very good chance, that they will feel at home, navigating this easy to use software. I've found the software to be very intuitive to use.

The only thing required of the end-user, in essence, is to simply select what celestial objects they would like to have the Seestar S50 photograph. I hardly think that the entire system could possibly be made any easier to use.

The Seestar S50 smart telescope, would be well suited for anyone who enjoys, or is interested in the night sky. 
It would be fitting for anyone, ranging from being simply intrigued by the night sky, and especially deep sky objects – to someone who always wanted to take photographs of deep sky objects, but wasn't sure how they'd begin.
This runs the gamut to someone who has previously tried Widefield Astrophotography, or conventional Astrophotography.

This smart telescope would be well suited for anyone who is fascinated with the subject of astronomy. It would be well-suited for anyone who has owned a telescope in the past, and has dabbled in the hobby of amateur astronomy. 
I contend that those who have enjoyed conventional Astrophotography in the past, will really be blown away by both its simplicity and raw capability. And by this, I’m referring to the outstanding results which this unit produces. 

M27 - The Dumbbell Nebula
(Some minor post processing)


M13 - The Hercules Star Cluster
(cropped and post processed)


NGC 7635 - Also known as The Bubble Nebula
(only very minor post processing)


The following, could be considered my version of a Quick Start guide:
(although there's nothing wrong with the one provided)
  • Open the case, remove the Seestar S50 unit and plug it in via the provided USB cable, to begin charging it’s internal battery.
  • While waiting for the unit to charge, you can download and install the Seestar software on your smart phone.
  • When the unit is fully charged, as indicated by the red LEDs, it’s ready to begin taking images of objects in the night sky.
  • Again, the Seestar S50 excels at capturing images of deep sky objects (referred to as DSO’s).
  • You launch the smart phone app, connect to the Seestar S50 (This is via Wi-Fi) and you’re ready to select your first object to begin imaging.
No, I didn’t forget anything - those are all the steps.

Things like Polar alignment. Something which is a must, when doing conventional astrophotography don’t exist when using The Seestar S50. 
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 only is it not needed, but it cannot even be done! 
  • (2.) Having to take Calibration frames: Darks, Biases, and Flat frames - again, not required, and also not possible (practically speaking).
  • (3.) Having an autoguider to purchase, and then worry about.
  • (4.) Having to wait until the next day (typically) to sort through, organize, and stack your frames.
  • (5.) 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).

I found the GoTo system and pointing (finding) accuracy to be excellent!


NGC 2237 (aka Caldwell 50) - The Rosette Nebula 


Pros:
  • Requires almost zero prior knowledge of astrophotography. 
  • Features an intuitive planetarium-like software, enabling the user to explore & select objects to photograph.
  • Is rated to continue operating down to a temperature of -15℃
  • Has a built-in dew heater, which is easily turned on & off (via phone).
  • Features a built-in Duo Band nebula filter (which is amazing!). 
  • It may be used to photograph the Sun, utilising the (included) Solar Filter.
  • It may also be used for daytime/terrestrial (wildlife) photography.
  • The software gives you the ability, to easily join a worldwide network of S50 owners: Enabling you to share your "works" and "Like" other's. Like a "Facebook for astrophotographers" - Neat!

Cons:
  • Cannot enter Right ascension / Declination coordinates (for unlisted objects).
  • Exposures are "locked-in" at 10 seconds each (end user cannot [currently] modify).
  • Lower Megapixel resolution than The Dwarf II (2.xMP vs 8.xMP on Dwarf II).
  • There is currently a bit of a wait, after you order a Seestar S50 (they are still catching up on back orders, etc.). The Dwarf II may be had without delay.
I have a feeling I'll be revisiting the subject of smart telescopes on this blog again, in the near future. Believe it or not, there are some fundamental (yet simultaneously amazing) topics, which may still need to be discussed:

Like how these smart telescopes are changing the way many people enjoy the hobby of amatuer astronomy now... Astrophotography, to be more specific. 

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!
