Astro-Physics 2.7-Inch Meade Large Visual Back. This 2.7-inch threaded back allows the use of Astro-Physics 2.7-inch accessories with 10, 12, and 14-inch Meade SCTs. The AP 2.7-Inch Rear Cell Adapter was designed primarily to accept the popular 0.75 x 2.7-inch Photo-Visual Telecompressor (27TVPH), but it will also work well with other accessories.
- Combine it with the AP 2-inch adapter (ADA2003) or their thin 2-inch adapter (ADA20132) and you have an unobstructed 2-inch visual back.
- Screw in the AP ADA204 2.7-inch to 2-inch SCT Adapter and you are right back to the standard Meade 2-inch visual back.
- Attach the 2.7-inch to 6 x 7 Outer Bayonet Adapter (ADA2767) along with either of the STL Adapters for the 6 x 7 Outer Bayonet (ADA671 and 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-inch diameter on down in size can be used with this adapter, greatly increasing the versatility of your large Meade SCT.
Please verify that your instrument has a 3.25-inch male thread on the rear cell before ordering. This adapter does NOT fit the 16-inch or 20-inch Meade telescopes with 4-inch rear cells. The adapter is one-piece, machined aluminum and is anodized black. The overall length is 2.5-inches.
