Astro-Physics 2.7" Celestron Large Visual Back…

This 2.7” threaded back allows the use of Astro-Physics 2.7” accessories with 11” & 14" Celestron SCT’s. The AP 2.7" Rear Cell Adapter was designed primarily to accept the popular 0.75x, 2.7” Photo-Visual Telecompressor (27TVPH), but it will also work well with other accessories.

  • Combine it with the AP 2” adapter (ADA2003) or their thin 2” adapter (ADA20132) and you have an unobstructed 2” visual back.

  • Screw in the AP ADA204 2.7" to 2" SCT Adapter and you are right back to the standard Celestron 2" visual back.

  • Attach the 2.7" to 6x7 Outer Bayonet Adapter (ADA2767) along with either of the STL Adapters for the 6x7 Outer Bayonet (ADA671 & ADA672), and you have the maximum available light path to your STL Series camera, and easy image framing to boot!

Virtually any accessory from 2.7” diameter on down in size can be used with this adapter, greatly increasing the versatility of your large Celestron SCT.

Please verify that your instrument has a 3.29" male thread on the rear cell before ordering. The adapter is one-piece, machined aluminum and is anodized black. The overall length is 2.5".
