A bright comet meets a globular cluster

A few days ago, while using my astronomy planner app (SkySafari), I noticed an interesting event on the night of July 14: the comet C/2017 K2 (PanSTARRS) and the globular cluster Messier 10 would have been in the same field of view of my refractor telescope and imaging camera. I checked the weather forecast and it was clear, so I prepared my equipment for the night and when the sky was dark enough (around 11pm EDT) I launched my routine imaging process. Due to the comet motion in the sky I had to keep the exposure time shorter than usual, so I wasn’t totally sure about the results. But looking at the final processed image, it was a success!

Until the next time, clear skies!
