Hi Konstantin,
I've merged a fix for this. It will be in 3.6.8 which is about to be released.
I can't reproduce exactly your issue from the scheduler, but I can reproduce the issue in debug so I'm fairly confident my fix will resolve this. If not and you get a repeat of the issue just let me know and I'll have another look.
Regards,
John.

Thanks Konstantin, do you autofocus when you image G which triggers an autofocus, or are you autofocusing every 30mins or some other way?
What's happening is that a filter change to or from B is triggering a focuser move of 24 ticks which, with the 300 ticks Overscan you have set, creates a 324 tick out move following by 300 in. This takes a few seconds to complete but its just long enough to cause a conflict with the next autofocus. Its this conflict that causes the scheduler to hang. I've got a fix for the scheduler hang (I think) but we're trying to exactly understand the circumstances that cause the problem, and we haven't quite got there yet.
Thanks Kiril, I expect you're right, when you swap filters, capture will wait for the focuser to confirm its moved by the appropriate offset. The other way around this, other than adding the focus simulator, would be to set the offsets to zero so no focuser movement is required. Its obviously problematic where some setup expects a focuser (offsets) and some setup doesn't have it (optical train).
BTW, I think some filter wheels allow the user to specify an option to approach filters from 1 direction only to avoid the situation where backlash prevents the filter from seating properly in the slot. I've not used this myself but thought it might be of help.

Thx, would you be able to post a screenshot of your Filter Settings popup please?
We know specifically what the bug is, but are still trying to piece together the series of events that trigger the bug.

Thanks for the logs Konstantin, I think this is a bug in Focus. I'll work on it later today.

Thanks AstroMuni! I think HFR is the basic method that works well for everyone. My "Introductory" video on Focus covers that (although its a bit long). The other methods could be better in certain situations for more experienced users; its fun to play around!
