Most of my imaging is done during the work week simply because the weather gods don't deem that the weekend should be clear
When imaging from home I am on mains power and have dew straps so that's not a worry. The cold isn't an issue because I only go out to check it every hour or so. Past midnight I only need to check it every two hours or filter change (focus).
For visual, I very rarely go past 11:30 pm because I need to go to bed. I do not make it to my darksite very often for much visual. Having a moonless Saturday night does not come around very often
