By all measures this should have been a good galaxy season imaging night; clear, light winds, average transparency and seeing and not too cold at Harvard, MA. Setup and polar alignment went well. The auto-guider was working great. Everything was ready by 8:50 PM in time for my three hour imaging session. Of the 14 galaxies on my target list I managed to image eight by midnight. I considered going past midnight but my chilled fingers and toes said no. That yield was acceptable. Unfortunately I was off my mental game. In several cases I used the wrong exposure dark frame during sub frame acquisition. An inordinate amount of image processing with Paintshop Pro 2021 was necessary to produce the images below. If given another good galaxy season clear night I'll try to finish aforementioned target list while adding a few more. Equipment used: Celestron 8 with AVX mount, Starizona Night Owl 0.4X focal reducer corrector, ZWO ASI294MC Pro camera.
