Astro-Physics 2

5.0 out of 5 stars

Astro-Physics 2" Adapter for 11 and 14" Celestron 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.

Astro-Physics 2 Adapter for Big Celestron SCTs

By Kyle Patrick on October, 16th 2009

If you own a big SCT, and are still using a 1.25 diagonal, you are missing out on a whole new world. Using this adapter, which replaces the stock Celestron 1.25 one, allows you to mount a 2 diagonal directly through, giving a tremendous increase in light to the eyepiece. The quality of this piece, like virtually all Astro-Physics items, is superb. My CPC 1100 GPS XLT is like a completely different scope now. Highly recommended, high quality, and inexpensive considering what it gives you with respect to everything from planets to DSOs.
