Yes, that was taken just last night, with an old school Barska Magnus 80mm APO, that cost me $259 brand new from Amazon 5 years ago. It still has the stock focuser, that can just, but barely, hold my Nikon D5300, bought used, and modded.

It was mounted on a used Orion Atlas ($800) bought off of Craigs list. Toss on a QHY5L-ii and an Orion mini 50 finder for a guidecam/scope  and I had consistent 0.6" to 0.8" RMS guiding for the 3 hours it took to take this 37 X 300" stack.

I'm still waiting to get my 8" Newt, sold so I can buy the AT115 for tighter shots than my AT65EDQ, so I had to dust off the old Barska, now that Galaxy Season is in full swing.

The edges of the frame show the severe "Pacman distortion" I've always had to deal with, but modestly cropped down like this , I think it does pretty well for a $260 OTA

( The entire background is awash in IFN , when viewed with an STF stretch in PI, but I would need a "few" more hours to get a clean image of it.)

Moral lesson for "newbies", put your money in your mount !!! ( You can take a reasonable photo with anything you put on it !)

I was prepared to see another blurry junk astrophoto, had my full snarky warming up. But you're exactly right. That's a nice pic. That you got it on the relative cheap is impressive on a couple of levels. Instructive. Skilled. Nicely done.

Hey 17.5 a job well done especially for the price and the time it took to guide for 3 hrs.

“Not too bad for a $249 OTA” is an understatement. It’s pretty amazing you got this photo with that scope. Well done!

*cough, cough*

 

also, beginners .... a little bit of experience sure helps

(No way Dave is a raw beginner!)

 

But I do agree with his moral - you can image with anything

Nice image! But these two statements seem inconsistent, no?

Living in Colorado is also a great improvment to imaging says someone living in Europe.

Moral lesson for "newbies" put yourself to a dark place with steady skies. If you can.

 

Great image!
