Description

I keep battling away with my Cassegrain, and getting round stars and good guiding is very difficult for me, in spite of precise balancing. So, as is per normal every month, I try during the moon's cycle, when it is brighter, to try and perfect this scope. This is 88 subs at 2 minutes long each, using the 8" Cassegrain at f8, rather than f12. It is RGB only. The nights are so light now that I am getting 1 hour's worth of astronomical darkness, maybe... I am struggling to get the data, but this is my best effort. Thanks everyone! N.B. 2 hours and 56 minutes was the integration time.
