2.7" Prime Focus Field Flattener for 130 f/6.3 StarFire GT (67PF562)

Brand :

Estimated Late August 2022

Our 2.7" Field Flattener (67PF562) can be coupled to a variety of different cameras for truly superb photographs or images with your 130 f/6.3 StarFire GT that has a 2.7" focuser.   If you have the 130 f/6.3 StarFire GTX or GT with 3.5" focuser, consider the 13035FF.  

The 67PF562 is no longer recommended for the 130 f/6 StarFire EDFS due to increased capability of current cameras. A new field flattener for those scopes will be available in late summer 2021. 

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, you may order them separately.

35 mm SLR or DSLR Camera
- For full frame Canon and Nikon DSLR's, we 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.
