Eventually Windows comes up without turning the computer into a brick. It's after midnight but what the heck - tomorrow is Saturday and I can sleep in so I start again. Running 5 minute subs, check the second one and after 4 hours in the cold of course I've lost focus. Delete those subs, spend a bit of time really nailing the focus and then start again. Two really nice Ha shots of Trifid and then.... cloud!!
Definitely finished for the night now. This can be a frustrating hobby!
