Description

M13 holds a special place in my heart since it is the first deep sky object I saw through a telescope eyepiece. While I think that star clusters tend to look better in the eyepiece than in the camera it is still worthwhile to image them to see the things that elude all but the larger telescopes. Processing is definitely a challenge to keep the densely packed stars from looking like a bunch of blobs on top of each other.

This was a pretty short integration but it was actually fun to process and try to preserve detail without it looking overly processed. I hope I succeeded on that front.

Details on processing are in the link on my website.
