Thanks Paula & David
Here are another couple of shots, again straight out the the camera, no noise reduction or processing (only resizing)

I'd done no scouting of locations to the sth, so was driving around somewhat blind, trying to find a spot with a clear view south and some foreground interest.
There goes my theory of an early night, before I knew about the aurora activity I'd planned to be tucked into bed by 11pm, seems the sun had other ideas
