John,
A little more about my equipment. I have two imaging trains, one uses the EAF and a filter wheel the other does not (a second camera on another scope for plate solving). Last night I was only imaging with the optical train that uses the EAF and the Filterwheel. I did plate solve with the second system, but I never ran a focus routine with it. I did run a focus routine on that system in my last outing, but it does not use the EAF, so I only loop with it while I adjust focus manually using a Bahtinov mask. I don't know if somehow the system could get confused about what was bing used to image, however the imaging last night worked with the filters, I was just not getting automatic focus adjustments.
