A lovely group of captures there Chris! You must have had a reliable power supply to get so much in through the night and into the morning. I had a go at M31 on Monday night but I only got about 30mins on it as it swept amongst the trees on the horizon. It was also very dewy and hazy. The scope was virtually horizontal to the ground. From what I can see in my subs, there is nowhere near as much detail as you've achieved, I may post it if I think it's worth showing. Your North American nebula is great and that 5 min sub of M42 is amazing for such a short integration time. Nice work!
