2.7" Prime Focus Field Flattener for Legacy StarFire f6 EDFS Refractors (13027FF-EDFS)

Brand :


Our 2.7" Field Flattener (13027FF-EDFS) was introduced in February 2022 for our legacy 130 f6 Starfire EDFS scopes that were produced from 1995-2001 in order to provide optimum performance with modern cameras.  It can be coupled to a variety of different DSLR and CCD cameras for truly superb images.   

If you have the 130 f/6.3 StarFire GTX or GT with 3.5" focuser, consider the 13035FF.  If you own a 130 f/6.3 StarFire GT with a 2.7" focuser, order the 67PF562

The backfocus spacing for these flatteners (as measured from the rear flange) is 86.4 mm +/- 2 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.

Two beautifully machined and black anodized covers.
