Globular Cluster M13 in Hercules

Globular cluster M13 in Hercules, imaged with  iTelescope T14 on June 21. The image is a stack of 5x 120 second luminance images (Bin 1) and 1 x 120 second Red, Green and Blue filters (Bin2).

Luminance images were stacked in ImageJ then the red, green, blue and stacked luminance images assembled using the Merge Channels tool. Click to embiggen.

It's official, I suck at colour astrophotography. :-(
