Spring galaxy season is here. Before the clocks change and the nights shorten, I've decided to do a few galaxy pictures. Here is M51. Focus and guiding where a bit out, and the strong wind didn't help. I have not bettered any previous attempt at this object, but I am pleased to get close to my earlier efforts!
