I have one more question about the auto focus routine in SGP. As you can see from the graph in my previous post I am only getting about 1.5x difference between the bottom of my curve and the top. I keep reading that ideally you should try and get 2 - 3x difference. Is the fact that I am only getting 1.5x difference a reason for concern?
Currently my backlash comp is set to 300 and the step size is set to 120. Should i consider increasing both? If yes, by how much? I hate to mess with it too much as I am getting such a nice V shaped graph right now (it took me a lot of trial and error get get my graph to look this good). My seeing was crap the other night when I was trying to get this to work so a HFR value of 6 was about the best I could get while focusing on Polaris.
Thanks again for all the help.
