Product Description
This full aperture filter has a 101mm/4" clear aperture Type 2+ glass filter element. It's mounted in an aluminum cell with a 133mm/5.25" internal diameter to fit scopes with a maximum diameter of 131mm (5-1/8").
It fits the Astro-Tech AT90EDT triplet refractor, as well as older Celestron C-102 and Apogee refractors.
You can custom fit it to scopes with an O.D. down to 127mm (5") by using the extra supplied self-adhesive felt.
