This is a snapshot of Comet C/2021 A1 (Leonard) on November 3, 2021, taken using a small 60mm APO doublet.

I captured and integrated two 60 minute sequences of 3 minute exposures to show the comet's motion against the star field near URSA Major.

This is my second test on the comet, intended in part to test feasibility for amateur-grade small scopes.
