NGC 1893 and visitor

Gregg Ruppel

Hi all:

I started collecting data on NGC 1893 (also IC 410 and Sh2-236), the open cluster and complex emission nebula in Auriga a few weeks back.  Then a few days ago I noticed that comet c2020 M3 ATLAS would be passing through the field on 12/8.

Here's the field before the comet arrived:

HaLRGB, 30.8 hours exposure for the cluster/nebula with an additional 40 minutes for the comet.  Captured with CCD Commander from Dark Sky New Mexico.

Clear skies,
