C/2021 A1 Leonard and globular cluster M3
Comet Leonard approaching cluster M3. Taken from Monmouthshire, U.K. on the 2nd December 2021. A rare cloudless night here. This was a stack of six 30s exposures with a Nikon D750 and 180mm f/2.8 Nikkor lens at f/3.5 and ISO 2500, processed, a little, with Affinity. This was taken around 03:40 in freezing conditions! I used an Astrotrac on a Manfrotto tripod to follow it.
