I wonder if the following feature could be considered? If there is already a way of doing this, please accept my apologies for bothering you. (And please let me know how!)
Following a night’s imaging, my focuser has usually racked a fair way inwards from the position it started in at the beginning of the session. When I start imaging the following night, it is usually too far inwards (from the previous nights imaging) to get a decent focus run straight off. So, at the start of every session, I have got into the habit of backing the focuser out by a couple of hundred points using a Coarse Focus control setting. This is repetitive, and occasionally I forget to do it.
I wondered if it might be possible to build in an end-of-sequence step that backs the focuser out by a user-adjustable number of steps. Of course, I appreciate that this might not be a ‘bullet-proof’ solution since a sequence might abort early in the evening before temperatures have fully dropped. Nevertheless, there is usually no real harm in being a bit too far out at the start of an autofocus run (I’d certainly rather be a bit too far out than in). And in any event, so long as the ‘feature’ was fully user adjustable, people could choose to use it or not. Maybe we could have a ‘Return to Sequence Start Point’ feature rather than a ‘fixed amount’ feature.
What do you think?
