Tele Vue 0.8x Reducer/Flattener for 102 Scopes
The Tele Vue 0.8x Reducer/Flattener for 102 Scopes reduces telescope focal length to 80% while flattening the field for up to 35mm frame formats. Although optimized for TV102 scopes, it also works with any non-flat-field refractors (such as doublets or triplets) from 800-1000mm focal length.
This 0.8x reducer, RFL-4087 can be used for all Tele Vue 102mm f/8.6 telescopes: TV102 and TV102is.
It is optimized for 55mm back focal length typical of SLR camera bodies that accept T-Rings. You must attach Tele Vue adapters TRG-1072 for standard T-ring or CWT-2070 for Canon Wide T- adapters, to the back of the reducer. For all telescopes with 2″ focusers, you must attach Tele Vue adapter RAD-1074. For the Tele Vue TV102is, the front female threads accept threaded extension tubes TLA-0250, TLB-0375, TLC-0500, TLD-1000, as necessary to focus with the 2.4″ focuser of this scope.
The RFL-4087 together with RAD-1074 and camera adapter comprises a replacement for the previous REF-3007.
This combination can also be used for other telescopes in the 800-1000mm focal length range for increasing field size and flattening the field for up to 35mm format SLR/DSLR bodies.
