From the explanation

“Imaged on July 15 2022, comet C/2017 K2 (PanSTARRS) had a Messier moment , sharing this wide telescopic field of view with globular star cluster Messier 10. Of course M10 was cataloged by 18th century comet hunter Charles Messier as the 10th object on his list of things that were definitely not comets.”
