M 13 Globular Cluster

M13 Globular Cluster
M13 LRGB

I revisited this as I think I've learned a few things about what I want in an image of a globular cluster. I left the luminance out, and just did RGB, being careful not to saturate any stars in the center of the cluster.

I wanted to see if I could get a little deeper using longer exposures, without saturating all the center stars.
