DESCRIPTION

Astro-Physics 2" Visual Back for Celestron 11" & 14" SCT

This 2" visual back threads onto the rear cell of Celestron 11" to 14" SCTs with 3.29" male threads on the telescope's rear cell. It provides a full 2" unobstructed opening (unlike most visual backs).

Use the AP 2" Celestron Large Rear Cell Adapter with 2" accessories that slip in, such as a. 2" diagonal, Barlow, 2" eyepiece or binocular viewer. This visual back features AP's 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.


Note: Celestron Edge HD scopes have a restricted rear cell that may not allow accessories with a long nosepiece to fully seat in this adapter (the AP Maxbright diagonal will not seat). It is recommended to choose the ADASCTLC27 and ADA2003 (or ADA20132) as an alternative when using the Edge HD scopes.

Well built visual back

I needed a back to mount my field rotator. The AP version was recommend to me. It is solidly built and mounts up to my OTA and rotator perfectly.

Needed for CPC 1100

Not sure why the "stock" backing on the 1100 is only 1 1/4". You would figure the purpose of large diameter is to collect more light. Why then does Celestron not use the 2" back? Maybe they want you to buy their 2" backing. I have seen their offering and it is not as solid as this one. This unit is built well. It threads right on with no tools. It uses a brass compression ring instead of set screws; very nice. The extra 3/4' makes a huge difference for my astrophotos. Also really nice to be able to use a 2" 40mm super wide lens. Again, not sure what Celestron was thinking. Definitely a good buy!
