It is a 2.5 min exposure which has picked up the airglow.

I have unmodded Pentax K1 and K5 bodies. My mate had a modded Canon 6D and an unmodded 5Dmkiv. The pickup by the cameras was quite different. One night the 6D would pick up strong airglow and the Pentax didn't, other nights the Pentax picked it up more than Canon.

Interesting. I once did a side by side between Sony A7r and Canon 5D3. The Sony looked better straight out of the camera as the Canon looked muddy whereas the Sony colours were good straight out of the camera plus it showed the green airglow. Canon's of course clean up in processing but I took it that the Sony had a better metering for white balance.

So it may be something to do with the white balance setting?
