On Monday I headed out into the wheatbelt with the D810, FSQ and the G11 to see what I could see. Low temperatures (-2C) certainly kept the noise levels down and I was also rewarded with a nice auroral display as I packed up in the morning.
I used ISO 6400, and although noise isn't an issue I wonder if I'd get more subtle contrast and detail if I'd used a slower ISO speed. Certainly, the subs were limited to 2 minutes by the sky. This is about an hour's worth (33 x 120s)
Processing in pixinisght - background subtraction, levels and curve, a mild unsharp mask and saturation boost.
