Description

First light with my new ES ED127 FCD-100. Took a little to overcome some hurdles (all my own doing) and for the weather gods to sync up with my work gods, but Markarian's Chain is a target I wanted to shoot for some time now. I know I don't have the full chain, but I will leave mosaics for an exercise in my future.
