Mars 2018 June 12

This was the start of my Mars observing campaign for the 2018 apparition. My method for coping with the very low altitude (no more than 17º) is to use the C-14 at native focal length (f/11), so obtaining a very bright image through an IR filter, and taking many thousands of very short exposure to stack (24,000 in this case). The seeing was very poor in this case, and I stacked only the best 12% of them. I used the 1.5x Drizzle function in Autostakkert! to enlarge the image.
