Well miracles happen we had a four hour window were the sky cleared last night so we managed to get out and have a quick session so chose the Western Veil as a target. The details are below the stars are slightly out of round so I think I have inadvertently moved the adjustable spacer between the flattener/reducer and the camera so the next clear night will be spent fine tuning this again making a note of the exact distance and then probably machining a rigid spacer to do the job to avoid future movement.
