This is a beautiful piece of glass. Purchased in the hope that I could use it on my f9 RCOS, but this idea was conjured up many years ago when the CCD cameras were much smaller. Consequently, I cannot get the required reduction with the STXL11002 I am using on the scope.
So, it was screwed in once, and has not seen daylight since, hence is in a 'as new' condition
