Description

The Great Globular Cluster in Hercules. Widefield image with the WO GT81 with RGBHaOIII filters.
I had a rather low amount NB subs which i think was a major cause in the hot pixels. I didn't patch them in post processing because i'd rather have true-er data. The weather has been terrible lately so here is what i've been working on.

Thanks for viewing and clear skies.
