Description

NGC 5216/5218 - Keenan's System

GSO 6" f/4 imaging Newtonian on an Astro-Physics Mach1 mount. 229 x 8 seconds with a ZWO ASI290MM at 300 gain. Frames acquired with SharpCap Pro and processed in PixInsight.

The version of the ASI290MM I have is uncooled. That coupled with a very warm evening and no dithering resulted in some nasty fixed pattern noise. Regardless of mediocre results I was able to (barely) pull out the stream of interaction between these two galaxies in the stretched inset image.
