$400.00

TeleVue's TRF-2008 0.8x Reducer/Flattener converts the TV-85 refractor to a 480mm f/5.6 system, and the TV-76 to a 380mm f/5.0 system, for flat field, fast photography. The multi-coated 3-element unit inserts directly into a 2" focuser, and accepts standard T-rings for 35mm cameras.

"This accessory is a must-have for someone planning to use the TV-85 photographically" - review in Sky & Telescope, July 1999. Also it can be used with any 400-600mm focal length refractor.

Note: The Televue 0.8X Reducer/Flattener for 400mm - 600mm telescopes was designed for an optimum 55mm back focus (distance from flange surface to film or CCD plane.) If you use a CCD camera, be sure the spacing between flange and CCD is 56mm +/-2mm for best results.

Requires an M48 wide T-ring (sold separately).

M48 wide T-rings for Canon, Nikon and Sony cameras can be found on our webstore.
