Description
Designed to be used with: Current 2.7” Prime Focus Field Flatteners (67PF462, 67PF562 and 67PF582) and previous 2.7” and 4” Prime Focus Field Flatteners (67PF69, 67PF79 and S155EDFFF)
This DSLR Camera Adapter for Nikon cameras with its enlarged inside diameter forward of the Nikon bayonet helps minimize vignetting on full frame chips. The limitation is only the camera body’s opening.
The adapter body is precision-machined aluminum and is anodized black. The bayonet is machined stainless steel, and both the body and the bayonet are baffled and painted flat black on the inside. The adapter was developed to be used exclusively with 4″ and 2.7″ Astro-Physics Prime Focus Field Flatteners.(Please note that the Starfire 175EDF, 160EDF and 130GTX CCD Field Flatteners and Telecompressor Correctors have their own large diameter EOS Adapter, the ADATCCNIK).
The 67RLNIK will position the chip (or film) at the correct distance from the Field Flattener optics for pinpoint stars.
A 48 mm internal thread allows the use of a filter in the optical path; however, double-stacking is not possible when used with a flattener.
The optical section of the 2″ Advanced Convertible Barlow (BARADV), along with the 2″ Barrel Extension w/ 48 mm Threads (A3703) can utilize these internal threads for a 2x magnification with central flat field (flattener not used) when used with an APS-C size sensor. This configuration requires using the 2.7″ to 6×7 Outer Bayonet Adapter (ADA2767).
This adapter and the ADA2767, along with full frame Nikon DSLR’s can produce easily framed images with a wide variety of configurations.
This adapter has a net spacing distance of 1.57″ (39.9 mm).
The spacing distance from the 48 mm internal threads (when using a BARADV or CCDT67) is 1.26″ (31.9 mm).
Note: If you received your 2.7″ Field Flattener prior to May 1994, you will need new aluminum parts to use this adapter. Please call Astro-Physics for details.
