Jeff, seeing slowly improved during the night. I was using a scope that I'm currently star testing and this night was a great test. Cracker of a scope - I managed to see details around 500m in size on the Moon. Previously with the orange tube C8 I had I could manage just down to 1.5km. 500m is roughly 0.3" of arc. Damn near peed myself!
PS, I looked up the resolution limits for an 8" scope. What I quoted at 0.3" seems way too small! I came to this size by identifying some of the smaller craters that have a dimension given in Virtual Moon Atlas. I was then able to see much smaller craters beside these of known dimensions, and the shadows involved deduced their size, and hence came up with the 500m size. Simple trigonometry using the distance to the Moon as 384,400km, and I came up with 0.3".
