Messier 55

One of the few Messier objects difficult to observe in the northern hemisphere, this is also the first light photo from the acquisition of a Skywatcher Esprit 120ED. As I'm still waiting for some adapters to be machined to match the included field flattener, I had to settle for a Baader MPCC II coma corrector. I'm still pleasantly surprised with the result.
