The center of the Virgo cluster is the first target I tried on a new camera of mine five years ago. The performance of the camera was very impressive, but I wasn't quite satisfied with the depth I achieved. Earlier this month, I doubled its total integration, from 5.2 to 10.8 hours. Now the outskirts of the galaxies are smoother than before and I don't need to apply too much noise reduction in post processing. I am also surprised by the large number of globular clusters in M87 detected in this picture (and the lack of in M86, which is interesting). I think I have reached the limit of my camera and scope. I am not going to spend another 10 hours on this target.
