Yeah, a 51mm refracting astrograph (RedCat51) and an ASI 294mcP is well undersampled.   I kept 49x 180 second exposures yesterday morning (Dec 02) and processed them purely in PixInsight.

The comet is approaching Messier 3 and transited the globular cluster during my daylight hours - what's worst than being clouded over? 

 

Be sure to check out the full resolution here https://astrob.in/yo7j4k/0/ on Astrobin if you get a chance.  I think you'll be somewhat surprised what a small refractor can do.

 

Best of seeing,

Dan

Not to shabby for a 51mm scope IMHO.  Thanks ifly and B 26354 for the comments (I'm blushing) and others for the likes.

Ha! Not too shabby for any aperture, in my opinion!

 

I lived in Lone Pine for a few years, back in the early '90s, and did a lot of hiking and some cross-country skiing in your area. Sure miss those black skies!  biggrin.png

I don't know about anyone else, but but I'm digging M3 in the zoomed image, which is pretty fantastic for any size telescope. There's some comet or something off to the right too, I guess, for folks who like that sort of thing. grin.gif

 

Inspiring work! bow.gif

A "pearler"?  Thanks I think Darryl (the emojis says it all - really thank you!).  B23654, Lone Pine, Mt. Whitney - rugged but beautiful - skies are still pristine(unless there's smoke from the fires.  Thanks Paul, Dan, danny and George for the addon comments - they are enjoyed.  Thanks for the additional likes also.  I was very surprised how this little scope setup performed.

Best,

Dan

Dan, I saw this on astrobin not long after you originally posted it and to be honest, I was in disbelief it was taken with a 51mm refractor. M3 looks so well resolved. Outstanding work on this.

(RedCat51) and an ASI 294mcP

 

That is the combo I am eyeing.

 

And undersampling makes for killer sharp photos.

Thank you!  The maps say Bortle 2 skies but I would argue since I'm at an altitude of 7700ft, thin dry air (less light pollution scattering) and my cabin sits up at least 200 more feet above the surrounding lakes on a granite dome.  The town's electricity went out one night last summer, and the skies looked the same - not exactly dark, as I might have expected, but seem to glow with their own light.  Probably altitude sickness on my part.

tboss70, and hence the title "Excited"!  I was pleasantly surprised to say the least.  Thank you!

With this scope I'm undersampled with every camera except asi290, 462 and 183.  And only if I have average to very poor skies.  Good or excellent skies I will be undersampled with even those camera.  When I actually purchased the RedCat51, before mass production, it was under a quick starter program with a minimal reduction of cost.  Some small changes have been made to the scope, since,  of which are inconsequential for my purposes.  A little pricey for a small scope but the promise of a wide flat field for comets allured me See: get.jpg?insecure  Excuse my comet processing skills of the time.  I' won't use it for planetary though.  Good luck with your decision!
