About this image

I thought the session would be hopeless, clouds kept rolling in, so kept losing guide star. Moon uncomfortably close by. Master APT program kept crashing. The last straw was when I realised that I had not properly manually engaged the blue filter in the filter wheel and lost the edge of the blue images. Anyway I persevered and managed to salvage the attached from only about 1 hour of good imaging. Main stars are a bit over-exposed. Never-mind, all a good learning experience under challenging conditions.
