Description

Messier 13 (M13), also designated NGC 6205 and sometimes called the Great Globular Cluster in Hercules or the Hercules Globular Cluster, is a globular cluster of about 300,000 stars in the constellation of Hercules. It is about 145 light-years in diameter, and it is composed of several hundred thousand stars, the brightest of which is a red giant, the variable star V11, with an apparent visual magnitude of 11.95. M13 is 22,200 light-years away from Earth.

I'm starting with astrophography and was trying to capture a color shot, but I confused myself with the correct setting for the camera in INDI. I thought I'd go ahead and post it.

Processing was performed with PixInsight 1.8.5 using BPP, ABE, MaskedStrech and Histogram Transformation.

Description: Actually, this was a color image. I missed specifying the debayer pattern in BPP. Here's the color version.
