I'm finding that morning twilight is the best time for imaging. This is a result from Sunday morning at 5.39am - not long before sunrise.

I set the scope up at sunset and then just tried to get the mirror down to the right temperature by 3am using a peltier cooler. After that I just switched everything off and let it sit until 4.30.

I imaged 700 frames in each of red,green,blue through filters and then batch processed 100 frames of each to give me 7 masters for each colour.

Finally combining those 7 masters in each of red,green,blue gives this result.
