So I had to give K2 another go after watching everyone having so much fun imaging as the comet proceeds southward through Scorpius. I moved my equipment to the very edge of the granite dome my cabin is perched on, and there I was able to image K2 as it set between several peaks of the Eastern Sierra Mountains in California USA. The sky was surprisingly steady and transparent on the 19th (not so much last night). Full resolution can be found here:https://astrob.in/7mkgdd/0/ Imaging details: WCS transformation .......
