Tele Vue 0.8x Reducer / Flattener for TV-76, TV-85 and other 400-600mm Focal Length Refractors
" the o.8x Reducer/Flattener performs superbly. Star images are perfectly round to the very corners of the field, and there is minimal vignetting. A high magnification examination of the images reveal little, if any, secondary colour even at the edge of field. This accessory is a must-have for someone planning to use the Tele Vue 85 photographically" Chris Cook writing for Sky & Telescope, July 1999.
The 0.8x Reducer/Flattener converts the Tele Vue 85 to 480mm f/5.6 and TV-76 to 380mm f/5.0 for flat field, fast photography.
Fully multi-coated 3-element unit with 48mm filter thread. Inserts directly into 2" focuser and accepts standard T-rings for 35mm cameras.
Can also be used with any 400-600mm focal length refractor.
