Description

It's been several years since I shot this group, and I was anxious to try it on the big scope. Unfortunately I wasted time shooting the moon because I mistakenly thought this was behind a tree, I left the bahtinov mask on, couldn't use the autoguider because it was too high for the guidescope to clear the dome slot, had to use a higher ISO than normal, etc. Still managed to get a good image despite my best attempts to screw it up.
