A murky night with scattered high cloud and lots and lots of moisture. Very humid - which resulted in a very damp telescope by the end of the night. I decided to simply whack the CLS filter onto the camera, and rove around the sky a bit in 2x2 binning mode.

This is perhaps my deepest crescent nebula so far. To do any better I think I need a hydrogen alpha filter
