Incoming Comet ATLAS (C/2019 Y4) on March 26, 2020 as shot through a 100mm f/5.8 apo refractor (the SharpStar 100Q) for a field of about 3.5° by 2.5°. A very faint ion tail is visible extending away at 2 o’clock.

This is a stack of 8 x 4-minute exposures, median combined, with the Canon EOS Ra at ISO 1600. While the comet did move slightly over the 30 minutes of shooting the median stacking minimized the trailing of the comet image.
