Comet Leonard (C/2021 A1) on the morning of December 10, 2021.


Comet Leonard (C/2021 A1) on the morning of December 10, 2021, with a 200mm telephoto lens. The tail appears to be about degrees long here. Taken about 6:30 am MST with the comet as high as it would be, though the sky is already beginning to brighten with the blue of dawn twilight. The distinctive cyan tint of a comet's coma is prominent. The comet was in Serpens at the time, with the magnitude star Alpha Sepentis (aka Unukalhai) at far right (I framed the image to include the star). The reddish double star 47 Serpentis is below the comet.
