Got Myself A Serious Tracking Mount - A (used) Skywatcher Star Adventurer

 So, I was shopping around (all over, actually) for a Star Adventurer tracking mount. I was on eBay, Astromart, and Cloudy Nights classifieds for a little over three days...

When, finally, someone listed one (on Astromart) - with just about all the accessories (except the small green anodized ball head mount). And I snatched it up; within hours of it being listed.

Seller's Orig Pic

The Seller was a really nice guy, and shipped it out right away. And for the first few nights, it worked great! Polar alignment doesn't even have to be perfect in order to get nice (trail-free) exposures of between 30" up to 2'! - Depending on how well you're polar aligned.

The Seller included a heavy duty ball head
 

I've even been keeping myself busy buying even more accessories and doo dad's for this mount...Including a new ball head holder, etc., etc.

For now, I just wanted to state: That although my astrophotography attempts have been easier than ever before; and some of the results I'm getting have been better than ever:

In all honesty, I still don't think I'm 100% "all in" when it comes to AP. I'm into it for now, strictly because of the close-to-freezing Temps we're facing over the next couple of months. 

The only way to enjoy any kind of astronomy, is via AP - where you can set everything up outside on a deck, take 15-20 Min. to frame & focus, etc., and then retreat back inside. While the equipment diligently takes the sub-exposures for you.

The bottom line, it seems: is that I much rather be enjoying the simple pleasures of observing DSO's and creating pencil sketches. The simple joy of using a telescope (or binoculars) to observe.

The first (and ever looming) issue, when it comes to AP - Is the cost. It's an expensive hobby. Especially if you want to do it right.

Mind you, this is coming from a guy who used to use a homemade barn door tracker ($25) as a mount! My entire AP set-up cost me about $600 (with camera, which was bought modified, for ~ $300+). That was my first foray into AP...while living under Bortle 8 skies.

Then, I moved to Bortle 4ish skies; and things were great. I was still using the barn door tracker, and getting good results. Short sub-exposures, though. Then, I got out of AP. Sold my modified Canon, and all the AP goodies.

Now, we moved to some solid Bortle 4 skies. So...I tried it again. By acquiring this Star Adventurer mount, etc. But - Here's a spoiler: The mount is currently for sale, right back on Astromart and Cloudy Nights.  ((sigh)) ...Well, I tried.

I guess what bugs me the most (these days) is the necessity of taking Darks, Flats, and Bias Frames - Ugh. Annoying.  

But, if we really get down to brass tacks - It's the expense. It's just naturally an expensive hobby. Much more expensive, in my estimation than even Mini Reef Keeping (marine aquariums). A person can set-up a very small ("Nano Reef") of a few gallons -to- 5 gallons in size, for much less than it takes to get started in AP.

YouTube is practically littered with videos on exactly how to do it. From 0 to thriving mini-reef aquarium in under $300. It's just an example...

Anyway, the expense - That's what's been "bugging" me lately. Most likely, because as of late, I'm on a lower budget than ever. Plus, the idea (mostly, the simplicity) of just observing (and maybe sketching) DSO's with an optical instrument has a quaint appeal to it.

What I've been fascinated with lately, are vintage optics. Vintage telescopes, both reflectors and refractors; as well as binoculars. I have even contemplated selling my Star Adventurer mount...so that I can buy a nice, vintage telescope. By this I mean something like a Tasco, or Edmund Scientific 4.5" reflector... Or a 76.2mm Tasco refractor, or any of the other desirable vintage models. Again, the only thing stopping me - are these really cold temperatures...

If you're one of the 3 people who occasionally visit this blog, and you have any opinions/thoughts to add on this subject: Please do!

To be continued...

Clear and steady skies to you!

Finally Found A Vintage Refractor! An 80mm Equatorial-Mounted Unit from Sears.

Well, I finally managed to find a vintage refractor - And I'm very happy about it! I had been wasting so much time on eBay... Ugh!

I decided to put an Ad up on Cloudy Nights... And Bam! I got a whole bunch of replies from some nice fellow Astronomers. So, the first thing I needed to do, was to mark my Ad as Found.

The next thing, was to reply to everyone who responded (in chronological order).

Then, print out their replies, etc. and keep them for future reference...And if you're an Amateur Astronomer, I don't have to explain why...

One fellow has a nice Sears, which I hope to be going with - but, my plan, will be to contact each of the other fellows - in chronological order - Each time I need a new addition :)

I feel very fortunate - And when I'm ready to add the next vintage scope to the fleet...I'll know exactly who to contact.

In the meantime, this is the 80mm beauty from Sears (Model #

Which will eventually find it's way to me here in New York, for some Winter observing (and sketching!).

 

Sears Model 4454, 80mm, F15, f=1200mm

 

Above, is a Sears Model 4454, 80mm, F15, f=1200mm which I was hoping to get... A gentlemen on one of the Astro buy/sell sites mentioned he had one...But I never heard back (re: this model). So, I ended up with this one:

Circa 1970 Sears Model 4 6333 A

Review of The 2 In 1 Move Shoot Move Star Tracker

I recently purchased a star tracker from Move Shoot Move. This was the kit (configuration) which I ordered - Basic Kit A:


MSM Easy to use Star Tracker (Newest 2-in-1) - Holiday Sale is ON! ✨

Basic Kit A: Rotator, Polar Scope, Scope illuminator, Scope Bracket

 

Check it out Here!

 

I placed my order online, on October 19th (2021).

I opted for getting my order from The US warehouse.

This option may be selected for an additional cost of $5.95. It was supposed to help me get my order quicker (as per their website). Move Shoot Move Have warehouses in Australia, Europe, and the US. 

Well, the fact is it took a while for my package to actually arrive. Below I've pasted the status updates, from the USPS website. As you can see, there weren't any changes for quite some time. Being very anxious to receive the tracker, I made it a habit of checking the package status everyday. The same status (as seen below) remained unchanged until October 25th. If you happen to be very anxious to get (back) into the hobby (like me!) it may be a little frustrating...

The MSM website does advise the buyer that they should expect delivery to be between 1 and 7 days.

Well, The MSM Tracker did finally arrive. And I was pleased with the excellent packaging.

I really liked the nice, cushioned carry case included -

The Polar Alignment scope is very nice, well-built (Aluminum) with the ability to focus; as well as 3 easy to access Allen screws for calibration (centering) of the reticule. 

Alignment and centering (calibration) of the reticule simply requires a bit of time and patience to get sorted properly. There is a helpful YouTube video, giving a good general idea on how to do it Here.

As other reviewers have mentioned, the only occasional issue I've run into, is: Ending up with a few shots (images) with minor star trailing. This happens (as others have reported) from time to time while the gears are getting "settled". Or "re-settled" after the mount has been moved or had any gross adjustment done to it. It seems to take a few minutes for the gears inside to settle back into their (accurate) routine.

If you take your time, and handle the mount very carefully, without overloading it (with anything larger than a 135mm lens) then your chances of success increases.

I only ran into issues when trying an 80-200mm zoom lens, on my Canon T7 DSLR. 

Again, the bottom line is: Get your mount properly polar aligned, don't treat it roughly, and it works just fine. I was able to get decent, trail-free images:

I used a 18-55mm Canon zoom (kit) lens; and managed to consistently get 30 second exposures, easily without trailing.

I look forward to adding much more to this review soon; as well as some of the pics I managed with The MSM Tracker.

This is a stack of 18, 30-second images, taken with an un-modified Canon T7 + 55mm lens - Using The MSM Tracker.

 

Until then, Clear skies!
