I just wanted to give a brief update. I have not been able to perform the test using the exe file Jared created to prove/disprove the centering concern. the weather has not cooperated and now I will not have access to do any imaging until the end of July. Not sure if anyone else would be willing or able to do the test to help out.
Backgournd informaton: I do notice for my rig I consistently get to approximately 80 pixels +/- 10 pixels but it will not converge any closer. It just seems to be very consistent around the 80 pixels. My image scale is 0.69". I'm using a ATIK 8300L+ OSC camera, 5.4um. at approximatley 1,610mm FL on a CGEM-DX mount. with the StarSense HC. I did try awhile back doing some testing with and without a model in the mount and it didn't appear to make a difference in being able to converge. that was using 2.5.1.12 beta I believe.
