A few globular clusters are still to come, but the end is in sight. Messier 92 is the 6th of a total of 9 globular clusters that I photographed in May and June using the VC200L and the EOS R, with consistent equipment and workflow.
M92 was the second object of the night and was photographed from around 1:30 AM to 3:30 AM.
