2.7″ to 6×7 Outer Bayonet Adapter (ADA2767) Astro-Physics

Description

This adapter greatly increases the versatility and functionality of your imaging system. It was designed to couple larger format CCD cameras like the SBIG STL series and full frame DSLR’s (such as Canon and Nikon) to focusers and accessories that have the female Astro-Physics 2.7″ thread. These include all Astro-Physics focusers, any other focuser that has an adapter with our 2.7″ female thread, large Celestron and Meade SCTs with our ADASCTLC27 and ADASCTLM27 adapters or the Photo-Visual Telecompressor (27TVPH). These are the advantages:

• Allows the Photo-Visual Telecompressor (27TVPH) to be used with a wide variety of digital and CCD cameras.
• Maintains the full 2.7″ unobstructed light path and does not vignette. This is particularly useful when combined with the Telecompressor (27TVPH) for connection to cameras.
• Allows rotation for easy framing of your image with hard-coupled configurations to DSLR and CCD cameras.
• Allows the use of the Astro-Physics adapters that were designed for the Pentax 6×7 bayonet system (used with our Field Flatteners) to be used without an Astro-Physics Field Flattener. Important Note: This adapter will no longer fit the outer bayonet of the original Pentax 6×7 camera (consider the ADA67P instead).

This adapter has a net spacing distance of 0.20″ (5.08 mm).

The ADA2767 is black anodized, and the inner 2.7″ clear opening has knife edge baffles that are painted flat black. The adapter is approximately 0.85″ in overall length, but adds just 0.20″ to the light path.
