Thanks. I understand what you are after now.
Also fair. I guess we would need more feedback that let us know if the current AF algorithms leave users in a position outside of their CFZ. Determining the smaller step size would be frustrating for some because of its sensitivity (another thing to train). This value would ideally be the minimum number of steps to produce a meaningful change in HFR. Unfortunately, HFR will vary even without moving the focuser due to camera SNR and environment. Definitely something to think about...
AF is already a very expensive feature for us... It consumes a great deal of support time and limits the number of new features we can produce because of it. I'm all for new stuff around AF, but at this point:
- It must be necessary for a bunch of users (meaning that, regardless of tuning, the current implementation will never likely produce acceptable results)
- It must not add more complexity to AF (and, as a result, the time required to support it)
