Weird! Yeah I’ve never had that problem
From my settings, I allow it to image for 3 minutes past the meridian before it executed a flip, and I usually take 60 second subs, but it’s happy to keep taking them. It’ll even start a new sub with only a few seconds left on the countdown timer.
A mate of mine had problems with SGP crashing whereas I didn’t...and we run almost identical hardware (Intel NUC, SW mount, ZWO camera).
My general sentiment is that software is written by humans, and no software is immune from problems!
