Big aurora tonight and Saturday?
The forecast is higher than usual tonight and Saturday -- probably because of all of the solar flare activity. Man, do I wish I could just drop everything and head North!!

Wow!! Judging by how sharp the stars are in the background, I am guessing that this exposure was at 10 seconds or so -- and judging by the lack of electronic noise, I am guessing an ISO of less than 1600 -- maybe 800? And the trees in the foreground are in perfect focus, so an f stop of at least 4?
How do you get these amazing shots? And isn't that Cassiopeia in the top right, behind the top of the aurora?
With my Canon 7D with the 10-22mm wide angle lens on it, I prefer:
6 or 8 second exposure, to keep the stars sharp. More time than that and their movement blurs the crispness too much for my liking. Last night was a 6 second night because the moon was so bright.
Last night I was shooting at ISO 1250. On a dark night, might bump that to 1600. Any higher there is too much "noise" for my liking but on really dark nights I might take it to 2000.
f/3.5 - completely open. Different lenses might not have the same aperture ability.
Good hardy tripod that can pivot the camera in every direction and that functions well at -40 even. Then 2-second delay on the shutter, so there is no shake. I have a remote shutter but don't use it as it is fussy in the cold.
