This combination focal reducer and field corrector converts the optical systems of f10 Schmidt-Cassegrain telescopes to f6.3 for photographic imaging.
Offers a wide field of view with Schmidt-Cassegrain telescopes and reduces exposure time by a factor of 3.
Fits both Celestron and Meade SCT telescopes. Optimal back focus to camera chip is approximately 105mm.
Note: Not suitable for the Celestron EDGE or Meade ACF series.
The Reducer/Corrector is f/6.3 for C5, C6, C8, C9¼ and C11 telescopes and f/7 for the C14 telescope. This reducer will also work well with many other instruments that have the standard SCT rear cell including the Meade LS, LX90 and LX200 series.
If offers wide fields of view with any Schmidt-Cassegrain telescope. Used for astro imaging, it reduces exposure time by a factor of 3, only recommended for standard 1.25" eyepieces when used visually.
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.
Please note - this reducer is not suitable for Celestron Edge HD versions which require dedicated reducers.
