2.7" Prime Focus Field Flattener for 105 Traveler EDT/EDFS (67PF462)
Brand : Astro-Physics
Discontinued: No Longer Available
- Please refer to the information below for historical information and recommendations.
December 2021: The 67PF462 is now out of stock and is no longer available. We recommend the Field Flattener for 92mm Stowaway and Traveler (92FF) for your imaging needs.
The following information is provided for your reference:
Our 2.7" Field Flattener can be coupled to a variety of different cameras for truly superb photographs or images with your Traveler.
The backfocus spacing for these flatteners (as measured from the rear flange) is 3.4" +/- 1/10" (86.4 mm +/- 2.5 mm).
The bayonet male thread size at the rear is 3.725" x 24.
Use the bayonet locking ring to secure your camera into position after you have framed your image. This allows you to rotate the camera to achieve your desired composition.
Starting in August 2009, all 2.7" field flatteners are now shipped with machined aluminum covers for both sides of the unit. If you already own one of these flatteners and would like a set of covers (CSET27FF), you may order them separately.
35 mm SLR or DSLR Camera - use 67RT adapters (specify the t-ring that you need) to interface with the field flattener for optimum results in 35 mm film formats. For full frame Canon and Nikon DSLR's, we also offer the Large 1.875" diameter SLR Adapter with Canon EOS (67RLEOS) and Nikon (67RLNIK) Bayonets .
CCD Camera - Choose the appropriate adapter A1260, A1261, A1262, A1263 or A1265 to space the field flattener properly with your CCD camera. For SBIG STL Series cameras we also offer the ADA671 and ADA672 Adapters which couple directly to the STL's accessory block for an unvignetted light path.
