Still getting used to the focus scale on this thing. It was a foggy night but it lifted just enough to get a few decent shots.

What are your typical settings for shooting the Auroras?

It varies depending on conditions but generally I'll have mirror lock-up and long exposure noise reduction on. I'll shoot on a tripod with a remote with a 2 second delay. ISO is typically up around 3200 or even 6400 so I can get a faster shutter speed to get some more definition, generally 5-10 seconds. And of course f/2.8.

Noise reduction on? You shoot in RAW I assume. Why wouldn't you turn off your NR and adjust it in post?

After 3 hours of straight, non-stop shooting the sensor gets pretty warm. I figure this method will reduce the amount of noise I have to fix in post. I could be wrong though, I've never actually tested my theory. Anyone want to chime in?

From what I've heard time is normally doubled when NR is on, I've never tested this out on my 6D. Maybe someone else can comment on it? I know it's best to turn everything off so you have more control over your pictures in post. Otherwise, those are fantastic shots no doubt! The Auroras is one thing I must see before I die. I've never seen the Aurora Borealis and it's something I've always wanted to see as long as I can remember. How vivid are the colors to the naked eye? A faint glow, very intense, etc...?

Yes, with NR turned on the time taken does indeed double. I tried this on a few occasions when shooting the Milky Way in New Zealand. Basically the camera takes the same amount of time as the exposure length to reduce the noise in-camera. It needs to complete NR processing before it can take another picture. So if you're using intervalometers keep this in mind when you programme the intervals.
