SOME BACKSTORY:
Last time I posted a pic was when this forum didn't even exist and it was still the normal text channel version. During my untracked days (or nights) my max focal length for astrophtography was 90mm full frame equiv. I got some relatively nice pics of Andromeda galaxy and pleiades, but they weren't detailed and the max exposure time per photo was around 3-4 seconds. Anyways, with me FINALLY getting tracked (with an eq6r), I could use my beginner 80mm f/5 achromatic refractor (that I bought far earlier) for astrophotography. Instead of max 1 second subs and almost constantly moving the scope on a wobbly photography tripod and getting literally no results (SiriL couldn't stack it because of how much the target was moving), now I can get up to 60 sec subs unguided (60sec is the max my camera reaches lol) and I can leave it the whole night and go to sleep, allowing me to get much, MUCH more integration time. I got this mount for my bday, but blew the whole budget on it, so for a year I'm stuck with this scope and a 4/3 sensor mirrorless camera... oh well, I don't have a field flattener so the edges have some coma and field curvature, but even with an insignificant crop the image is actually well corrected and usable, which really gets to show just how great value this little refractor is. The focuser is actually decent and smooth even after 2 years, and except for no field flattener and some blue color fringing this scope is basically perfect.
Photo info:
My camera gets some issues while taking many 60 second photos and shuts down and stuff, the max I can currently do is 40 seconds, and that's what I did here.
