Had marginal seeing last night and I believe a focus failed (see the long exposure) but the script continued to run for 7h until the AM when I manually aborted it?

I wonder if bad weather would have shut down the roof in such a situation?

What I see is a 10 second exposure that lasts over seven hours! Something got stuck with the camera. Did you happen to see anything strange on the system? Normally ACP has a timer that will stop an exposure at 3x the requested (a rare "oops logic" in ACP). But it got really stuck, like when it checked the camera status it called MaxIm and never returned, leaving everything stuck.

The problem is that ACP needs to intervene in order to have your roof safely closed. Were it not for the low-hanging roof, the weather sensor could just close the roof and keep your stuff safe.
