I shot this image between July 24 and August 25, at my “Cabin in the Sky” roll-off roof observatory, which is located in the south Okanagan region of British Columbia. A brilliant blanket of red emission nebulae encompasses an intricate web of reflection nebulae of varying shades of blue, with the field shot through by stars of many vivid colours. Towards the middle of the frame the blue nebula fades gradually in colour and intensity, giving way to very dark clouds in an apparent transition that seems almost unique in the sky!
