Long story short, this functionality was fully implemented, but was never migrated and released. Focus logging enhancements needed for characterization were released, but the remaining code (automation of trendline coefficients, and the config file / control code) were only sent to Jasem and a few others for testing. Jasem thought a GUI based control would be nicer than a config file, but no developer was found to do that (not my skill/desire). I subsequently offered to give the code to anyone who wanted it, but there were only a few takers. Old habits die hard, and most people don't mind running focus repeatedly on a target during the night (especially if it's automated, regardless of whether those runs waste a lot of time).

For me, I could never go back to "standard" Ekos focus methods. An initial "seeded" focus run per target, followed by apriori trendline based focus adjustment between exposures, keeps emphasis on imaging, avoiding a lot of wasted time "re-finding" focus. For a while I tried to keep pace with new Ekos versions, but IMO there was too much "tinkering" and a bit too much instability being added to justify continuing that. Once I found a stable, non-crashing Ekos version that I could trust and served my purposes, I stayed out of the fray. The reality is that until folks care more about the amount of time being wasted on focus, there's no need for this feature. The hobby's gear is heavily biased at f/5 and longer, and as a result, those of us who are super-sensitive to focus (f/4 and shorter) are in the minority and need to fend for ourselves. If interested in the code, send me a PM. cheers, Doug
