Orion Field Flattener for Short Refractors




Optically fast refractors used for astro-imaging are often burdened by substantial field curvature. This is especially evident when CCD imagers with APS-C sized and larger sensors, or DSLR cameras are used. The convenient Orion field flattener solves the problem by supplying excellent field correction while maintaining the focal length attributes of your telescope.



This Orion Field Flattener is made for short refractors with focal lengths between 400 and 600 mm, and focal rations between f/5 and f/7.5. It allows you to take advantage of the full imaging capacity of your fast refractor telescope. 38 mm clear aperture optics, full multi-coatings and a glare-reducing threaded interior guarantee peak image contrast.



This Field Flattener is compatible with 2" focuser drawtubes and is favorably threaded to be used with 2" filters. With 55 mm back focus required, Orion recommends their T-thread Spacer Ring Kit for obtaining proper distance for use with CCD imagers. DSLR usage requires a T-ring for the camera. These are both sold separately. Weighs 7.5 oz.
