I just had a go at DeepSkyStacker and played around with it. I had Darks and Offsets in there too, but no flats. Now I know what they are, I will have to do some later. Anyway, I threw a few in together and this is what I got. It was a couple of images in each, exposures about 50 seconds ISO1600 Celestron Nexstar11GPS on alt-az tracking. Prime focus with a Canon400D.
Is that how you write them up?
