0.8X Reducer/Flattener converts TV-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 inserts directly into 2" focuser, 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 refractor. Brings an ED80 back to 480mm f/6 for wider and flatter fields!
Used in prime-focus imaging, reducers increase photographic speed while flatteners decrease image curvature away from the center. Star images are perfectly round to the very corners of the field.
