Description

When I went outside tonight I planned on trying to image the Blue HorseHead Nebula. However Scorpius was not high enough in the sky yet. I decided that I would image M56 while waiting for
Scorpius to move higher in the sky. It's been a while since I imaged M56 and I've never really gotten an image that I was pleased with. For me M56 is a difficult object to image and I really don't know why. When compared to some other globular clusters M56 is relatively small and dim.
It is also compact and doesn't have a lot of stars in the outer regions of the cluster. When I finished imaging M56 the sky clouded over and I did not get to try and image the Blue Horsehead Nebula. Please enjoy my latest image of M56.

On my monitor the image looked OK. However on Astrobin gradients were very obvious. I attempted to flatten the background a little.
