I need advise on processing etc. I went out a week ago in front yard and got about 10 to 12 exposures @ 8 seconds each of M31, and a handful of darks, no bias, no flats and processed in DSS and Gimp. Not great, but not ridiculously terrible. I went out last night and got about 40 exposures @ 15 seconds each, with 20 darks, flats and bias. Again processed in DSS and Gimp. Why does the 1st image seem better than the others that were done "properly" with lights, darks, bias and flats? I don't understand. Also, why is bottom 1/4 of image blown out and so crappy? I tried gradient tool but no luck really. The moon was high and bright both nights so not ideal conditions but I had nothing else to do so went out for a bit and my boys wanted to tag along so we had a good time goofing off and looking through scope. Anyway, can someone please take a look and point me in right direction? Maybe even try to take my stacked unprocessed files and see if can even get a decent image stretched out of it (not sure how to do that unless I email to you or upload somewhere but need all help I can get). Needless to say, after watching a million youtube tutorials on this I am highly frustrated. Why is this so fun yet so frustrating? I guess I am a glutton for punishment or just chasing that holy grail of images.
Test 1 image is about 10 x 8 seconds with about 10 darks ISO 3200 if I remember correctly
Test 2 is about 40 x 15 seconds with about 25 darks, bias and flats 1600 ISO
Test 3 is about 40 x 15 seconds with about 25 darks, bias, no flats as I was just trying to experiment. 1600 ISO
