Red light

Hi Brett, great image!
I have found that light from a red headlamp near the camera viewfinder will give a red area on the picture. Canon warns of this in the manual for my 60da in the Bulb photography section. There is a small rubber sleeve attached to the camera carrying strap that is for sliding over the viewfinder during prolonged exposure when stray light may enter the viewfinder. Normally it is not noticeable, as we shoot prolonged exposures in the dark. Don't know if that affects your camera but worth considering.
John
