C/2020 V2 (ZTF) 2022-Dec-20 Dan Bartlett

C/2020 V2 (ZTF) has just finished transiting 11.1 magnitude elliptical galaxy NGC2300 and 11.4 magnitude spiral galaxy NGC2276 earlier that late afternoon for my vantage point. The IFN scattered about and my processing ability lends to a messy presentation.

Here again I've included an annotated version, an inverted color, plus a cropped field view and two early stage "CometOnly" versions (hinting at a possible 2nd tail). What a mess...
