Comet Erasmus (C/2020 S3) on Nov 22, 2020, 4:50 AM to 5:40 AM. 50×60 sec sub-images captured in SharpCap 3.2, QHY183c at -20C cooling, Gain 20, Offset 200, Optolong L-eNhance filter, Televue TV-85 at F/5.6, dark, flat, bias calibration, Metro area, Bortle 7-8 zone, clear and average transparency, seeing was poor for comet elevation (under 12 degrees.)  Star-Freeze version.

New comet discovered in September, 2020 in the morning sky at twilight.  Very low and very hard to image from the metro area I’m in.  I used an Optolong L-eNhance filter, which helped beat back the terrible LP I had to image through when it was less than 12 degrees above the horizon.
