Product Description
This Stellarvue photographic field flattener and reducer is made exclusively by Stellarvue. It is designed as a full-frame, dedicated reducer/flattener specifically for our SVX130T and SVX140T apo triplet refractors. It reduces the f-ratio on the SVX130T from f-7 to f-5.6 reducing its focal length to 728 mm. It reduces the f-ratio on the SVX140T from f-6.7 to f-5.4 reducing its focal length to 750 mm. As with all Stellarvue-designed photographic flatteners, these units have a very long back focus to accomodate using a variety of additional accessories. Stellarvue will match the camera thread and back focus of your imaging train as long as your camera thread is one of these: M42, M48, M-54, M-68, 2.156"-24, 3"-24.
Unlike former reducer/flatteners we sold, two of the elements in this multi-element reducer flattener are made using low-dispersion, fluoro-phosphate glass. All elements are fully-multicoated with broadband coatings designed for astro-imaging. The unit is large and designed to work with 3.5" focusers including Stellarvue telescopes sold with a 3.5" Feather Touch or the 3.5" Moonlight focuser. Contact us if your Stellarvue telescope uses another focuser.
