The option to refocus during capture already exists in Capture tab. But it works only with autofocuser and doesnt prompt user to manually focus This wishlist request has been placed in the past and its good to know that there are more users having a need for this feature.
SW130pds on HEQ5 Pro mount, ZWO ASI533mc pro, 30mm guidescope with ASI120mm mini. All managed using Kstars/Ekos on RPi with Astroberry build.
Thanks for the answer, it is good to know there are more people interested.
By the moment I didn´t face big problems with focus, but I think it is a big improvement and a garantee to know you are on focus during all your session. If not, you have to trust in your manual calibration and expect conditions don´t change much during the night.
Popup could be more or less as the rotator, showing if you need focus-in or focus-out, and the amount.
In my case, I don´t buy an electric focuser because the telescope will not fit in its case when assembled...
