Saving focus values to avoid need to autofocus between filter changes

spartinlimitless

Are there any plans to add the ability to save the EAF position value in the ASIAIR to avoid needing to refocus between filter changes. This could cut down on time wasted on focusing quite a lot.

Thanks for your time!

I think what you're describing is "filter offsets". There is another thread on this as well:

(And I agree 100% - I'd love to have the ability to set an offset and backlash setting, then only have to autofocus once at the beginning of an imaging session, not between filter changes.)

You do have to refocus when temperature changes sufficiently from the beginning of the sequence. But with filter offsets, one only needs to refocus with just one filter (usually the one that uses the shortest exposure time to refocus faster).
