Comet Leonard Dec 20th
Comet Leonard 2021-A1
Combining 89 images captured last night of differing exposure values, I have produced this HDR image of the comet. A couple of shock fronts can be seen and perhaps a gas ejection jet. I didn't attempt to remove the stars on this processing run. Estimated visual brightness during this run, mag 4.1-4.3 though with the comet sitting in the twilight glow and the comparisons stars Eta and Zeta Gruis, much higher up, I don't put high reliability on my estimate.
