Messier 12 (NGC 6218)

Globular Cluster in Ophiuchus      RA 16h 47m 15s  Dec -01° 56m 52s

Peter Branson took this image of M12 on the 28th June 2021. It was obtained by combining the best of 20x60sec images taken with an Atik 314L+ colour camera. This was used in conjunction with a TS Optics Photoline ED102 f7 telescope with a Hutech IDAS light pollution filter and field flattener attached and all mounted on an NEQ6 mount. This arrangement was guided with a separate guidescope using PHD Guiding. The images were combined and processed in Nebulosity.  Image © Peter Branson.
