I’m having an issue with autofocus being triggered after a slew and center to start a target, despite the fact that I had just focused with the same filter right before starting the sequence. For example, the first filter in my target is O3. I slew to a high spot in the sky and focus with the O3 filter. Then I start the sequence, which slews and centers on the actual target. The slew and center function uses the Lum filter for plate solving. After centering and starting PHD2, the filter changes back to O3. This is apparently being interpreted as a “filter change” because it triggers an autofocus routine again.
I believe this behavior is new. Has there been a change to the autofocus trigger that would explain this?
Thanks for any input,
