A truly rather rarely photographed object, and I’m glad I managed to capture it this year.
The last of 9 globular clusters that I photographed in one go this early summer. Most of them I captured in just one evening, including the beautiful globular cluster Caldwell 47, also known as NGC 6934.
This year, I really managed to achieve excellent collimation on the VC200L. It’s possible that for this image, the collimation left a little to be desired again, or perhaps the seeing was simply below average. The next season will surely come, and then a new collimation session will be due.
