Great Globular Cluster in Hercules

This is a redo. I've updated my Bias, Flats, and was a little more selective in the lights. This is 27 lights of 250 second exposures. Shot with QHY12 OSC on AstroTech 10" RC. (Also added a star spike on the bright star)

Very well done Brian, great colors.

Pushed it a little more, I think I like the softer one.

I used Jim's new found dpi and tried it out on this image. It probably will work better at the beginning of the process, but I think this came out pretty good.
I've never been happy with my dark parts of the sky, as they always had a reddish tinge to it. Using this higher dpi, I was able to remove that.
Very cool, thanks Jim for sharing!

I like both versions. Nice stars and exposure.

An awesome shot, how many light years away is that group?? 
22,200 lightyears away. It's radius is 84 lightyears. And there are several hundred thousand stars in this cluster.

And that is why I have been doing this for my planet shots.
I am glad that you found this technique useful.
Very nicely done.
