Agreed, and yes the M20 at AF was from a different location to the others but my point was that AF should have been massively better but didn't seem to be and in fact what shocked me most was that the ones from Nundah seemed to be better! My post was really one of incredulity

All the shots from Nundah were taken from the exact same location of course and the two Eta Carina's were there as a comparison of results with and without the moon and other early evening civil illuminations.
