More information

Starizona's SCT Corrector has been an incredibly popular focal reducer and coma corrector, giving astrophotographers with standard Schmidt-Cassegrain telescopes an improved optical system and wider field of view, with increased photographic speed. Starizona now offers a large-format version, the SCT Corrector LF, designed to cover full-frame (35mm format) sensors.

The SCT Corrector LF is designed for Celestron 11" and 14" standard SCTs. Designed to thread directly onto the large 3.29" threads on the rear cell of C11 and C14 telescopes, the larger optical elements of the SCT Corrector LF minimize the vignetting over large sensors. Remaining vignetting over a large field is minimal and limited only by the telescope baffles, which are designed for a slower focal ratio; but this vignetting is easily removed by using flat field images. Sharpness is excellent over a 42mm diagonal, with spots sizes up to 9x smaller than the native telescope! The focal ratio is reduced to f/7.2 on the C14 and f/7 on the C11, for a speed increase of 2.1x and 1.9x, respectively.

The SCT Corrector LF is designed to increase the available backfocus compared to Starizona's standard SCT Corrector. Backfocus is 146, accommodating a variety of accessories. The rear threads on the SCT Corrector LF are the same 3.29" threads as on the rear cell of the C11 and C14 telescopes, so standard accessories are easily attached.
