I am guessing you need to calibrate your 5 minute subs. 43 x 5min should give you a decent result if properly calibrated. At very least use flats to get rid of the dust motes. What processing program are you using?

Obviously I’ve done a lot wrong because my 20 minute image looks better than this one which is over 6 hours of data. There’s a whole heap of noise and I think dust motes? Also I think the top right quarter is light pollution?
Any ideas as to where I’ve gone wrong? Happy to post the original stacked image (before I butchered it �� ) in case anyone’s willing to take a look at for me.
