Celestron EdgeHD optics: corrected image, sharp to the edge!
EdgeHD is Celestron's optical design designation, the "Aplanatic Schmidt-Cassegrain Telescope." After more than 50 years of success, Celestron is revolutionizing the classic Schmidt-Cassegrain telescope.
EdgeHD (English: "Edge High Definition") telescopes are true astrographs. This optical system delivers sharp, distortion-free images right to the edge of the field of view. Not only is coma corrected off the optical axis, as with other so-called "coma-free" optical designs available on the market, but also curvature of the field.
Many optical systems are propagated as "astrographs". They obtain images of stars with the desired precision, but along a curved image plane. When taking pictures with cameras, the result is a striking field curvature that increases towards the edge of the field and is all the more noticeable the larger the sensor. The stars inflate into small rings ("doughnuts") towards the edge. In addition to coma, Celestron Edge HD telescopes also correct for this curvature of field all the way to the edge. This also significantly improves resolution and cut-off size compared to competing optics with a similar aperture.
Celestron's XLT multi-coating also helps EdgeHD optics achieve a significant increase in performance compared to similar systems on the market.
The mechanics and tube of the Edge HD telescopes have been completely revised:
Mirror locks hold the main mirror in any focus position without putting pressure on the optical elements. The image always remains stable on the chip, even with long exposure times.
The ventilation openings behind the main mirror ensure rapid air exchange, so that the optics cool down quickly without equal. Thanks to an air filter system, no dust enters the tube.
The Advanced VX is an ideal mount for mobile astrophotography with small to medium sized telescopes! The sophisticated features of Celestron's large equatorial mounts are now available for telescopes up to approximately 14kg. Thanks to PEC (Periodic Error Correction), the periodic worm error that occurs in all classic worm gear mounts can be compensated for, so that long exposure images are also possible. You can also track objects far beyond the meridian without having to move immediately. So you can observe the most interesting part of the sky without interruption. Additionally, the Advanced VX has a much wider base than its predecessor, further increasing stability even under heavy loads. The upgraded motors have more torque and are better able to handle a slight imbalance.
Experienced photographers will appreciate how easily this mount can be transported to a dark viewing site. If you're new to astronomy or astrophotography, the Advanced VX will make it easy for you to get started and serve you for years to come.
Mount accepts Vixen standard dovetail bars or Celestron wide dovetail bars (CGE standard), but not Losmandy 3" rails.
