C/2020 M3 (ATLAS) @ 2021 January 16, 02:43 UT

Comet C/2020 M3 (ATLAS) imaged on January 16, 2021, with a brightness at 11th magnitude, it was still somewhat difficult to observe because the comet was in a very populated area of stars near the Milky Way, anyway I was able to record a very faint and greenish outer gaseous coma of 3.5 minutes in angular size ,with a inner dust coma and a short tail backward in its orbit.
