Product description

More about the series Advanced VX...

This Schmidt-Cassegrain system combines the AVX computerized equatorial mount with Edge-HD optics.

With more than 23cm of aperture (9.25", SC 925) and StarBright XLT coatings, it gathers more than a thousand times more light than the naked eye alone. The excellent image sharpness means it is also an excellent system for astrophotography!

The Celestron EdgeHD telescope: Corrected image - sharp right up to the edges!

EdgeHD is the name for Celestron’s “aplanatic Schmidt Cassegrain telescope”. After over 50 years of success, Celestron has revolutionised the classic Schmidt Cassegrain telescope.

EdgeHD telescopes ( "Edge High Definition") are true astrographs. This optical system delivers distortion-free, sharp images right to the edge of the visual field. This means that not only the coma outwith the optical axis is corrected, as is the case in currently available “coma-free” lens designs, but also field curvature.

Lots of optical systems are advertised as “astrographs”. As desired, they display stars with pin-sharp clarity, but along a curved image plane. Photographing this using a camera results in a noticeable image field curvature which rises towards the edge of the image field, resulting in increasing star size and aberations with larger sensors. The stars at the edge expand into small rings (“doughnuts”). As well as the coma, the Celestron Edge HD telescopes correct field curvature right up to the edge of the image. This also significantly improves resolution and magnitude limits in comparison to rival optical systems.

The XLT multi-coating helps to give the EdgeHD scopes a significant performance boost compared to similar systems on the market.

The Edge HD telescopes’ mechanisms and lens tube have been fully overhauled:

  • mirror clamps hold the primary mirror securely in any desired position without putting pressure on the optical elements. The image is stable, even during long exposure times.
  • Air vents behind the primary mirror provide fast air exchange so that the lens cools amazingly quickly. Thanks to an air filter system, dust is prevented from entering the lens tube.

The Advanced VX is the ideal mount for mobile astrophotography using small to medium-sized telescopes! Telescopes up to around 14kg can benefit from the well-engineered functions of Celestron’s large parallactic mount. Thanks to PEC (Periodic Error Correction), the periodic error, which occurs in all mounts with classic worm gears, is strongly reduced, making long exposures possible. Additionally, you can follow objects far beyond the meridian, without instant switching being required. This means you can observe the most interesting part of the sky without interruptions. The Advanced VX also has a considerably wider base than its predecessor, which increases stability when carrying heavy loads. Improved motors have with high torque and can better compensate for small imbalances.

Experienced photographers will appreciate how easily this mount can be transported to dark observation spots. If you are just starting out with astronomy or astrophotography, the Advanced VX can help to make those first steps easier and provide you with good service for many years to come.

The mount takes Vixen-style dovetail rails or wider Celestron rails (CGE-style), but not 3” Losmandy rails.

It not only matters which telescope you buy but also where you buy it. Our additional services:

  • We are a leading telescope dealer and know the devices we sell. Our customer service team will gladly help you after your purchase if you have problems with assembly or operation.
  • We provide a copy of the 80-page "Telescope ABC" beginners handbook with every telescope.

Celestron Schmidt-Cassegrain telescope SC 235/2350 EdgeHD 925 AVX GoTo
EdgeHD optics provide an image plane that is three times flatter than with a standard Schmidt-Cassegrain. That means that stars are diffraction limited imaged over the entire chip with a Nikon D3 or Canon 5D camera!
