Schmidt-Cassegrain SC 235/2350 EdgeHD 925 AVX GoTo Telescope

This Schmidt-Cassegrain combines the computer-controlled AVX equatorial mount with the Edge HD system.

With an aperture of over 23 centimeters (9.25 inches), SC 925, and StarBright XLT coating, it collects over a thousand times more light than the human eye. It offers superb image sharpness, excellent for astronomical photography.

Celestron EdgeHD Optics: Corrected image, sharp to the edge!

EdgeHD is the name of Celestron's optical design, the "aplanatic Schmidt-Cassegrain telescope." After more than 50 years of success, Celestron is revolutionizing the classic SC telescope.

EdgeHD (Edge High Definition) telescopes are true astrographs. This optical system provides sharp, distortion-free images right up to the edge (or "Edge") of the field of view. Not only is off-axis coma corrected (as with other optical designs marketed as "coma-free" instruments), but also the curvature of the image field.

Many optical systems are advertised as "astrographs." They allow stars to be viewed with the greatest precision, but in a curved image plane. In images taken with cameras, the result is a noticeable curvature of the field that increases toward the edge of the field of view and becomes more noticeable the larger the sensor. Stars swell into small rings ("donuts") toward the edge. With Celestron's Edge HD telescopes, in addition to coma, this curvature of the image field toward the edge is also corrected. This also significantly improves resolution and limiting magnitude compared to competing optical systems of similar diameter.

Celestron’s fully multi-coated XLT coating also gives EdgeHD optics a significant performance improvement over other similar systems on the market.

The mechanics and tube of the Edge HD telescopes have been reworked from the ground up:

• Mirror locks hold the main mirror in any focusing position without exerting pressure on the optical elements. The image always remains stable on the chip, even with long exposure times.
• The vents located behind the main mirror ensure rapid air exchange, cooling the optics at an unparalleled speed. An air filtration system prevents dust from entering the tube.

The Advanced VX is an ideal mount for astrophotography outings with small and medium-sized telescopes. The most sophisticated features of Celestron's larger equatorial mounts are now also available for telescopes weighing up to 14 kg. Thanks to PEC (Periodic Error Correction), the periodic error found in all traditional worm-gear mounts can be compensated for, allowing you to capture long exposures. It also allows you to track objects beyond the meridian without having to immediately turn. This way, you can observe the most interesting part of the sky without interruption. Furthermore, the Advanced VX has a much wider base than its predecessor, further increasing stability, even under heavy loads. The improved motors have more torque and can better compensate for any small imbalances.

Experienced photographers will appreciate how easily this mount can be transported to a dark observing site. If you're just starting out in astronomy or astrophotography, the Advanced VX will serve you well and will provide years of enjoyment.

The mount is compatible with Vixen-type prism rails and Celestron wide prism rails (CGE standard), but not with 76.2mm Losmandy-type prism rails.
