Startron F6,3 focusing lens is suitable for 5 inch 6 inch 8 inch 9 inch 11 inch and 14 inch Schmidt-Cassgreen SCT telescope. This is a beautiful accessory that can reduce the focal length of the telescope to F6,3 without sacrificing image quality .
This defocusing lens/field correction lens accessory can be used on the Star Trang 5-inch, 8-inch, 9.25-inch, 11-inch and 14-inch Schmidt-Cassegrain telescopes. This flexible accessory allows the telescope to have two focal ratios without sacrificing image quality. This reducer/corrector can make the focal ratio of C5, C6, C8, C9.25 become f/6.3, and the focal ratio of C14 can become f/7.
Using this lens can increase the field of view and reduce the exposure time in astrophotography.
Star Trang does not provide the Schmidt Cassegrain telescope with f/6.3, because such a design is impossible, and there will be a large central occlusion that will cause the contrast to drop. This f/6.3 reducer/corrector lens is a 4-element design with coating on the entire surface.
Using this defocusing lens, it has a very good performance in visual and photography.
