Astro-Physics 2.7

Our 2.7" Field Flattener can be coupled to a variety of different cameras for truly superb photographs or images with your StarFire refractor. Each field flattener is designed for a particular focal length for optimal results. They are not interchangeable. For those wishing to adapt the field flattener to other cameras, keep in mind that the film plane should be 3.4" from the surface of the flange closest to the camera, +-1/10". (86.4mm +/- 2.5mm) This is true for all 2.7" and 4" field flatteners that we have produced except for the 160 Field Flattener (160FF).

Appropriate for 130 StarFire EDT, 155 StarFire EDFS, Star130ED, Star12ED, 5"f8 StarFire, 5" f/8 Standard.
