I couldn't agree more, astro with dark adapted eye not a good idea, for my eyes at least. We all have our own particular eyes, and a fair few of us think beforehand about the conditioning of our eye(s) in preparation for taking a sight. My only aim in suggesting the dark adapted eye 'test' with and without specs was to provide a demonstration of just one of those mysterious eye processes... Doing experiments on your own eyes is all part of the fun ....
