SCT focuser interface compliance about indi

[knro]

How would this fair with different clients? The driver should be conform to INDI standards and not necessary to how Ekos operates its autofocus.

The change I'm proposing is to align the focus driver with INDI standards - it is not currently. Presumably this would benefit other INDI clients. I completely get your point that the INDI drivers shouldn't be designed for Ekos only. I guess what I'm saying is that the existing driver implementation both isn't ideal for Ekos (at least not with AF overscan set) and also isn't compliant with INDI standards.

The more I've looked into this driver - the more confused I get. Backlash compensation, for example, seems to mostly replicate the Ekos AF overscan behavior (i.e. overshoot-then-retract applied to all moves in one direction) rather than a true backlash compensation (i.e. constant added to any move when reversing direction from previous). The overscan behavior is beneficial for SCTs when imaging - but I would prefer standard backlash compensation (without overscan) for visual use.

If it is to align with INDI standards, then sure go ahead! It would be great. Would this mean it needs to be changed in 3 places?

1. Celestron GPS driver
2. Celestron SCT focuser standalone driver
3. Celestron AUX driver

OK I'll get started on - it'll take a little while since I don't have much time these days.

1. Celestron GPS driver
2. Celestron SCT focuser standalone driver
3. Celestron AUX driver

Change will need to apply to both the Celestron GPS and SCT focuser drivers, but not the AUX driver, since that is already compliant.
