We expect to have these back in stock by early August. Sorry for the inconvenience.
This combination focal reducer and field corrector lens accessory works with all Celestron 125mm (5″), 150mm (6″), 203.2mm (8″), 235mm (9 1/4″), 280mm (11″), and 355.5mm (14″) Schmidt-Cassegrain telescopes. This clever accessory makes it possible to have a dual focal ratio instrument, without sacrificing image quality. The Reducer/Corrector is f/6.3 for C5, C6, C8, C9¼ and C11 telescopes and f/7 for the C14 telescope.
If offers wide fields of view with any Schmidt-Cassegrain telescope. For a 203.2mm (8″) telescope it means you’ll now be able to see the entire Sun and Moon through a low power eyepiece, using the reducer-corrector. Used for astrophotography, it reduces exposure time by a factor of 3.
Celestron doesn’t offer a f/6.3 Schmidt-Cassegrain telescope, because the design is impractical, with a large central obstruction, and resulting loss in contrast. This, added to the inability to utilize longer focal ratios for certain objects, led Celestron to design the four-element, fully multicoated f/6.3 Reducer/Corrector. Results are amazing both visually and photographically.
This Reducer/Corrector Lens is not compatible with Celestron EdgeHD optical systems.
