After resetting the config files (.PHDGuidingV2 and .phd2) last night I didn't see any spikes or issues with the centroid.?I think that something in the old config files was confusing it. I have seen this before, and have made a habit of saving off good config files, and restoring them before starting a session. I hate this kind of mystery fix, but there it is. I'm going to do a diff on a good config file vs a bad one and see if I can find an obvious issue with the config.?
So after resetting the config files I was seeing what looked like an improvement, but it's hard to tell with just last nights session. I'm going to toggle the multi-star next time to get a better understanding of the performance differences.?
