Welcome back Ken. Thanks for SGP and your dedication to it.
Max, I believe you can make a new target after all your Light frame events (or simply add flats to an existing target) and in the first flat event's options, choose the pre event Park scope. You can also set the post event option in your last light event to park scope and then move to the next event or target for flats.
I second the park and take flats routine and would like to see "flat park position."
Or for that matter, if SGP could...say in the equipment profiles store a Park Position and a Flat Park Position as Alt Az coordinates or land object coordinates and allow the user to set it in SGP with the mount connected (like it is now) but be able to adjust it finely by using the actual coordinate numbers.
