Update: It's a good seeing night, so I am running FocusOffset.vsb. I have five actual filters, and two open slots between Filter #4 and Filter #7 (yes, I know, not good, but it's too cold to make a physical change tonight.) Anyway, after ~28 focus runs, no disconnects of either the focuser or the telescope as each run completes. That's telling, but I'll see what happens when FocusOffset finishes.
