Description

This image was an afterthought and my first attempt of a Northern Hemisphere glob since my early DSLR days. When my primary target M81 and M82 sunk into the trees there was still some good imaging conditions left. Switched to M13 and was able to capture 9.4 hours of integration through LRGB filters before dawn over 5 nights.

The smaller galaxies NGC6207 (near bottom of frame at 7pm from M13) and IC4617 (at 8pm about twice radium of M13) are also visible.

Image taken with ZWO ASI1600MM-Cool camera at gain 10dB (0.28e/DN) cooled to -10C. 78 Luminance frames, rest RGB. Conventional processing in Pixinsight with large star halos reduced using Pixelmath.
