I have been trying to use the AT2FF field flattener with my Telvue 85 and Atik383 OSC and still cannot get the backfocus correct. The AT2FF asks for 57mm +/- 4mm and using the 17mm to the ccd chip I am using 60mm backfocus and still have stars at the edge that are out of focus.
Has anyone else used the AT2FF with a TV-85 and Atik383 and found the best backfocus distance? I will be doing another test using 61mm to see if the field flattening improves.
