I have a meade 911B broadband nebular filter for meade and other sct scopes-this filter screws on the back of the scope itself- not into the eyepiece. It is approx 2 years old and like new condition with original box. These sell for $94 new at anacortes. I am asking for $65 And i will pay shipping (cont. 48 states). I do not accept paypal, prefer check or money order.
