I would like to suggest the introduction of a new option (to my knowledge not existent) where optionally the user can set a time interval for auto focusing during the acquisition.

In my experience it does help, at least if the temperature is changing. I have seen a big reduction in FWHM in post processing after a manual stop, AF and then continue acquiring.

I did that because I was looking and noticed an image deterioration. But it would be nice to be able to program this. All remote telescopes I have used have this option.
