The aurora is forcasted at level 6 today and tomorrow (High +).


How do you guys shoot it with a DSLR. Shutter speed, f stop, ISO?
Any other tips for us Aurora virgins?

Thanks and enjoy everyone.

a. Lens aperture as wide as possible, and set to manual focus all the way to infinite ()

b. Depending on the brightness of the Auroras, and how wide your lens can go (for example f/2.8). Bright 400-600 ISO for 8-10 seconds. Not very bright, 800 ISO for 10-13 seconds

c. Camera set on a tripod

That's pretty much what I use for settings. Saw some really neat lights this morning out here on Cook Inlet. Unfortunately I don't have my camera.

Thanks much. Went out tonight and saw a lot of stars, no Aurora. Must have been too early (9-10pm). Forecast is a 6 this Wed-Fri. Odd, same place a few days ago, forecast at only level 2, saw it pretty decent. That was around 1-2 am, though.

Friend coming from Anchorage tomorrow with a decent cam, hoping for some nice shots!

Kp can be as high as it likes - if the Bz doesn't turn, there won't be much dramatic visible northern lights activity. Unfortunately Bz is not readily forecast like the K-index is.

Shame to think of all that perfectly good solar wind going to waste because the magnetic field isn't cooperating!

Exposure also depends on whether the moon is out and the focal length. The thumb rule for exposure time is 400/mm (where mm is the focal length) if you do not want to see star trails. These days most DSLR bodies have made enough progress in high ISO performance that shooting at ISO1600 is no issue at all.
