Celestron Reducer 0.63x / Corrector

This dual-purpose focal reducer and field corrector lens accessory is compatible with all Celestron Schmidt-Cassegrain telescopes ranging from 5" to 14" in aperture. Its innovative design allows for a dual focal ratio instrument without compromising image quality. Specifically, it operates at f/6.3 for C5, C8, C9¼, and C11 telescopes, and f/7 for the C14 telescope.

Offering expansive fields of view with any Schmidt-Cassegrain telescope, this accessory is particularly advantageous for astrophotography, reducing exposure time by a factor of 3.

While Celestron does not produce an f/6.3 Schmidt-Cassegrain telescope due to practical design limitations, such as a large central obstruction and resultant loss in contrast, they have engineered a solution in the form of a four-element, fully multicoated f/6.3 Reducer/Corrector. The results are exceptional both visually and photographically.
