I provided an edit above, as you make a good point. I was frustrated with those uninformed with flashes, too, and realized that the inverse could be true, which is why I made this post. Here is the edit for expediency:

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.
