Last night I got to do my v curves run with the FLI atlas, GSO RC12 and STXL.

I thought it went ok until with a couple of exceptions.

The v curves were sort of lop sided towards the right with the center line. With the slope being shorter on the right than the left which starts at the top left. I was using 30 points and a 40HFD setting. The focusor would go from 21700 to 101500 with focus being at 68,000ish. There is plenty of travel left, but I am considering doing a 30HFD to make V curves easier. Perhaps it ought to be less.

The second thing and as can be seen in the attached image. The V curves don't look right. The PID's are not consistently close to each other. Peter.M suggested that this could be seeing related but not sure if that is the problem.

When I went to focus it would get to near focus and then it would endlessly try to get focus convergence. I had it set for 10 samples with the same but not one was the same as the other.

So aside from putting up a post on the Yahoo group, does anyone have any suggestions as to how to solve the problem. Am I missing something?
