MICROSOFT EDGE!!!
Got me too last night.
Dont know if the metered connection trick still works to stop auto updates?
Every W10 update breaks something on both my desktop and my new and old laptops and resets and reinstall stuff, which wouldn't be that bad if Microsoft didn't aggressively push updates, and I could actually just update when I decided I feel I have the sanity to deal with it.
I got eight 180s Ha and OII exposures of NGC7293 at the expense of sleep and sanity. I'd be very happy to end up with a result like yours. Great picture of a cool object, sorry you missed hours more data!
