Does fitting a good quality UV or Daylight filter to a 62 APO (or any APO) affect the lens performance detrimentally in any way? I'm unsure about fitting one to my new scope, trying it out alongside my non APO Televid 77 the colours are outstanding and I always thought the 77 was superb so I wouldn't like to suffer a slight drop in performance just to prevent damage to the objective lens?
