Edit
To provide some context given the messages below. I was a professional photographer, and understand that getting a good photo is a skill. Exposure time, timing, location, and many other factors come into play when capturing a great image.
Seeing the aurora was a fantastic experience. The purpose of this post is to help reduce FOMO of those who could not see it. Many people who don't know these things will imagine dancing lights in the sky of brilliance, and will be saddened by what they missed. While they did miss something, it's important for them to know exactly what they missed.
Edit2 I should also note this is why I enjoy when photographers post gear, conditions, and settings alongside results. It tells viewers what was real.
I think the biggest disappointment I had after moving to Alberta was finding out the Aurora Chaser groups use high exposure for all of their images and the actual aurora just looks like white beams most of the time. I do see green from time to time, but you need to go to dark-sky preserves or the fuckin' Yukon to see the good ones.
Aurora photos are a real circle-jerk of dishonesty.
high exposure is used on almost any high-level landscape photography, even during daylight and not exclusively auroras. there is nothing wrong with squeezing down a couple of minutes into one picture for a better visualization
Long exposure is used for basically all astrophotography
