The hot new activity of late winter/early spring in Manitoba (for better or worse) is aurora-spotting, thanks to an upswing in solar activity. The Northern Lights are notoriously fickle — one night they appear, the next they don’t and there’s no set time when they ‘usually’ show up. Forecasting is vague, but maybe it’s all these factors that make it so magical when it finally does appear before your eyes.

True to their name, the further north you go the more visible they become. Near the capital city down south, they are usually a glowing line on the horizon, but occasionally the output from solar flares or sunspots is high enough that shimmering bands of green and violet can appear overhead. Regardless, moving as far from city lights and its attendant light pollution will only make it easier to see, with the happy benefit of seeing just how many stars do fill the inky black night sky.
Happily, the regular cycle of our sun is tracking upwards, so the months ahead should give more opportunities to see (and photograph) them yourself.

On that note, these images were made with a DSLR and a wide angle (24mm) lens, wide open at f/1.4 and 20 seconds. Depending on your focal length, any longer than 20-25 seconds and you’ll start to have the stars ‘trail’ or blur from the rotation of the Earth. Some photographers crank up their ISO to 6400 or above in order to get much shorter exposure times, or because their lenses don’t open up past f/2.8 or higher — that’s a (somewhat) viable option now that digital sensors are so much better, but I prefer to keep my ISO as low as possible.
Also keep in mind that ‘infinity’ focus on your lens doesn’t actually focus on infinity! Simply turning your lens all the way to the infinity setting will result in blurry stars. If you have Live View on your camera, turn it on, zoom in on a bright star and manually focus your lens until it’s sharp, then leave your focus where it is and shoot away.

Good luck!

I had thought the aurora had died down for the night, and was driving home when one look through my rear-view mirror showed they had flared back up again. Did I mention the Northern Lights are fickle and unpredictable?
