Messier 10 - A nice globular cluster in Ophiuchus


Messier 10 is a globular cluster in the constellation Ophiuchus. It was discovered in 1764 and spans about two thirds the size of the full moon.


We imaged this target for just one 1 hour while waiting for Cygnus to be higher in the sky as our main target for the night was in that constellation. We usually don't image globular clusters with the small refractor telescope but we that was the only one we brought with us to the desert that night so we did not really have a choice!


M10 is best photographed at the end of Spring and beginning of Summer. Read our guide on the 15 best Astrophotography targets for Summer if you need some inspiration about what to image next!
