Not my best image, I dusted off an old f/4 Newtonian that I used to use for visual work and tried imaging with it since I sold my refractor and have nothing else to use for the time being. I think there are flex issues with the cheap focuser and the spacing for the coma corrector doesn't appear to be quite right. I did get to test out my new ASI1600MMC though. It hasn't been clear for literally months and although it was in the single digits, it was toasty in my portable warm room and nice to just get out and play with equipment!
