About this image

Combined exposures from 2022-12-13,2022-12-15 to give a total exposure of 150 min

Except for the strong CN emission line at 3900A, the inner (8 arcsec radius) coma spectrum is dominated by reflected sunlight from dust. The much weaker and therefore noisier outer (10-50 arcsec radius) coma spectrum however reveals Swan emission bands from C2
