This 0.8x reducer, RFL-4087 can be used for all TeleVue 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 TeleVue adapters TRG-1072 for standard T-ring or CWT-2070 for Canon Wide Tadapters, to the back of the reducer.
For all telescopes with 2" focusers, you must attach TeleVue adapter RAD-1074. For the TeleVue 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.
