Celestron's 9.25 optical system has enjoyed a loyal following since we first introduced it with our Ultima 9.25 in 1995. Now the 9.25 optical tube is even better with the addition of EdgeHD optics. The 9.25 is a favorite among astro imagers and discerning visual observers with it offering 33% more light gathering than our 8" model. CPC Deluxe 925 HD is specifically designed for astro imaging and optimized to reduce aberration across a wide field of view.

Celestron Origin stands at the forefront of a new era in amateur astronomy, blending stargazing and astrophotography into a single, user-friendly experience.

A traditional Ritchey-Chretien (RC) is a type of reflector that delivers a coma-free, flat field of view via hyperbolic primary and secondary mirrors. RC telescopes (from a variety of manufacturers) are found in most of the world's top observatories and NASA's Hubble Space Telescope.

The Ritchey-Chretien telescopes are a variant of the Cassegrain telescopes but with hyperbolic primary and secondary mirrors that are designed to eliminate off axis optical errors.

Keeping pace with the current rapidly developing technology environment the iOptron HAE69 and HAE69EC SWG mounts have evolved into the HAE69B iMateTM.

Sharpstar 140PH, a large-aperture APO astrograph, the very first in Sharpstar APO-series, finally comes to the market. It features pioneering double ED glass and triplet air-spaced lens structure.

The launch of Sharpstar SCA260, a fast-focal-ratio aspherical Cassegrain astrograph, fills up the existing service gap in domestic market. SCA260 is designed with an aspherical mirror.

ASI6200MC Pro uses Sony’s latest back-illuminated IMX455 Full Frame format native 16-bit ADC sensor. It has 3.76µm, ultra-low 1.2e readout noise and an innovative breakthrough resulting in zero amp-glow.
