Sometime we're so busy at sunset there's little time to take good sunset photographs. You just pop outside, take a couple of hand-held shots and head back inside to deal with whatever's going on. I took this on one of those occasions and it wasn't helped by some high winds. I'd started our observatory calibration sequences and popped outside quickly to watch the sun set before returning to the control room to sort out some problems we were having.
I'm not sure about this picture, it's a couple of hand-held pictures stitched together, but I like the colours and the lens flare!
