Astro-Physics 2" Adapter for 10" and larger Meade SCTs, with Brass Locking Ring.
This 2" visual back threads onto the rear cell of 10" and larger SCTs (3.25" opening). It provides a full 2" unobstructed opening (unlike most visual backs). Use with 2" accessories that slip in, i.e. 2" diagonal, Barlow, 2" eyepiece or binocular viewer. Features astro-Physics unique brass locking ring design and 3 large thumbscrews to hold your accessories securely and squarely. Ideal for critical applications. If you prefer to use just one thumbscrew on occasion (perhaps if you are interchanging accessories frequently), simply remove the extra 2 thumbscrews for that session.
Adapter cannot be used when the Microfocuser is attached to the LX200GPS.
