Last night I left my scope outside by itself and went to bed. I don't have automated flipping so I waited till it had crossed the meridian and set it off. This is my result from adding another 10 hours to my helix image. It is 23.5 hours of helix nebula in half hour subs, I think I will turn my attention to some O3 now.
I hope you like it, I have definitely noticed some difference between 10 and 20 hours of exposure.
I think it is modestly stretched to make sure there is no noise showing. I will probably give it a belting tonight when I get home from work to see whats there.
