This is a mylar filter in a very solid "plastic" mount. The filter is in excellent condition; No pin holes, tears or scrapes. There is a bit of felt adhesive residue on the inside of the holder because I used it on a 4" refractor, but this in no way effects functionality. This was used on a white C5+ scope. it is designed to slip into the front of the telescope; not over the tube. I suspect it will fit other Celestron 5" SCTs but cannot guarantee that.
Tuthill sells these for $85 new. I'd like $45 (includes shipping). Paypal payments accepted without any fees.
