About this image

This was a bright and colourful aurora (in the camera, still grey to my eyes) showed nice ray activity at times. I only observed it after midnight so no information about earlier in the night.

Hi there,

I was struck by the difference in colour between Callum and you. Many DSLRs have an automated white balance as default. I wondered if you use a different setting due to aurora being rather different to day time scenes.

Though, I suppose, the difference could come from differences in the leakages of the RGB Bayer matrices used in the cameras - I recall using a DSLR with an RGB Bayer matrix and taking pictures at 820nm, using only the light leakage in the pixel filters.
