As I currently only had a OSC camera I've been trying to think of what kind of imaging I wanted to do over the full moon period from my suburban back yard and decided this would be the perfect time to try imaging a galaxy
NGC 253 is large enough and bright enough that I don't think the moon matters too much, I'd say my biggest killer at the moment is shooting with a F/10 (F/4 would make SNR easier) at 0.4"/pixel
Anyway, I'm pretty happy with how the 3.2 hours has come up so far. Ended up with a FWHM of 2" which isn't fantastic by any means but it's the best I've managed with this setup so far. Given how bright the background is even at F/10 I am thinking about dropping my exposure time from 5 min to 2 min, could yield sharper results and I'm still 10-15x read noise.
For pixel peepers
This is about as good as it's going to get until I add another 20 hours of exposure.
