Description

Acquired on 7/20 and 7/24, one image before meridian flip and one after. This made it a real pain to align, and even with CCDStack, the alignment was not perfect, which I don't understand. Also, there was a satellite flare in one of the blue subs that I had to remove. Turned out ok I think.
