Description

With this image I tried out going for higher integration time - nearly twice as much as my previous maximum (5.8h). It was interesting watching the level of noise fade away as the number of subs went up over multiple nights. It wasn't really the best time of year for this target however - on the final night of imaging (5 October) it was only above 40 degrees for around an hour and a half.
