Home Forums Gear Photography Some Auroras

Thank you. The violet or purple colors can't be seen by the human eye, and are not always present in the Auroras. I just happened to be there at the right time, and had no idea that the violet colors were present until I looked at the photos on the camera's screen. I was very lucky that night

Why the different colors?
