Autofocus with L-Filter, configure Offset-Focus-Steps for other filters

dagerber

New configuration option for Autorun/Autofocus: after filter change, always focus with Luminance Filter, configure Offset-Focus-Steps for narrowband filters.

Autofocus after filter change takes a long time with narrowband filters, since I have to use long exposure times between 10s…15s.
It would be much better, if I could always focus with the luminance filter and configure an offset in EAF steps for all other filters relative to the luminance filter.
This is how most people focus with Software like Nina.
Would be great, if this would be possible with the Asiair as well, it would be much faster and also more reliable.

Great suggestion! I also would like to have some sort of automation to measure the offsets between filters relative to a selectable reference filter (not everyone has an L filter i guess)

I agree with this. I would like to see it as a function that can be turned ON/OFF in cases where you would not want to use it.

I second this. Was surprised to find that after switching to using an AA+ to control imaging there appears to be no way to add in the focus offsets needed by each filter. Instead do we have to do a full refocus after every filter change for mono?
Taking 30 minutes of images per filter before switching to the next in order to ensure something usable after one night means a significant amount of time spent focussing.

unixnut Thank you for your feedback, I conveyed to our ASIAIR team.
