How to shoot the Aurora
The basics of getting good aurora photos:
You should have a digital SLR (aka DSLR) so you can manually set the shutter speed, aperture, ISO and focus; mounted on a tripod, with at least one spare memory card and battery. It's easy to fill a memory card in one setting, and if you live in a colder climate, (which increases your chance of seeing aurora) batteries don't usually last very long, working in frigid temperatures. A tripod is essential, as it is impossible to hold a camera perfectly still for the length of time it takes to expose these shots.
Your aperture must be open to 2.8, (or as wide as you can get it). Anything narrower than f2.8 though, puts serious limits on the quality of your shots
The shutter speed will need to be between 8-60 seconds depending on the intensity of the light. If you're stuck with a narrower aperture than 2.8, you'll really need to be able to add more light by increasing your exposure time.
The ISO should be as low
