C/2020 M3 (ATLAS) 2021-Jan-02 Chris Schur

This spectacular scene involving a 1st magnitude G type star and a 10th magnitude comet is an imaging challenge to say the least. This one hour exposure was required for the faint comet which is a nice teal color here, but way overexposed the brilliant Capella. The comet here is within half a degree of this star, and fortunately did not end up under one of the huge diffraction spikes from Capella!
