F / 6.3 field reducer and corrector for Schmidt-Cassegrain telescopes. This optical element significantly reduces the focal length and exposure time in SCT telescopes.

Characteristics and applications

• the equalizer fits all Schmidt - Cassegrain telescopes offered by Celestron (except EdgeHD) and Meade
• the corrector has a male SC thread on the eyepiece side, so the telescope accessories are used in the same way as without an equalizer
• telescope focal length is reduced by a factor of 0.63 - 1000 mm becomes 630 mm, 2000 mm -> 1260 mm, 3000 m -> 1890; this allows the same surface brightness of the photo to be obtained after 40% of the time, compared to shooting without an equalizer
• properly selected equalizer curves flatten the SC telescope's field of view, offering a fully corrected field with a diameter of 24 mm
• the equalizer also improves the quality of images in visual observations - the sharpness at the edges is improved; we suggest using an equalizer in combination with 1.25-inch glasses
