Its probably light pollution but amp glow is a magenta colour.

Thanks Greg.
Used ISO1600 which gives a read noise of 3.9e- and a dynamic range of ~9.5 stones if memory serves.
I had 60x60s darks (just kept it going until it flattened the battery as the moon was up).
Pretty sure it isn't amp glow as it I didn't have the same problem with the LMC shot. It was probably the DBE struggling due to Barnards Loop.
