The Celestron EdgeHD Telescope Schmidt-Cassegrain SC 235/2350 925 AVX GoTo offers high resolution, long range and photographic perfection in one portable setup. This model combines the popular 9.25″ EdgeHD optics with the Advanced VX GoTo mount - a combination beloved by astrophotographers seeking ultimate sharpness and simplicity.
EdgeHD optics, flat field of view, razor sharp to the edge
Celestron's EdgeHD series is designed for modern astrophotography. Where classic Schmidt-Cassegrains exhibit field curvature, the EdgeHD 9.25 a perfectly flat image over large sensors. Stars remain round to the extreme corners, with no coma or astigmatism. This makes it ideal for DSLRs and dedicated astro cameras with larger chips.
With a 235 mm opening and 2350 mm focal length (f/10) the telescope delivers razor-sharp images with enormous magnification power. Both small planetary details and distant deep-sky objects are rendered with impressive clarity. Under dark sky conditions, the 9.25″ aperture reveals nebular structures, galaxies and planetary nebulae barely visible with 150-200 mm telescopes.
Mechanical precision and ease of use
The vents on the rear accelerate temperature acclimation, while internal mirror bearings minimize image shift. The 2″ visual back allows the use of wide eyepieces for a large field of view. The optics are also compatible with Celestron's 0.7× EdgeHD reducer, which shortens the telescope to f/7 - perfect for deep-sky photography.
The Advanced VX mount forms the stable basis of this system. This GoTo mount offers 40,000 objects in its database, automatic polar alignment via All-Star Polar Alignment, and PEC correction for long exposures without noticeable tracking errors. The sturdy steel legs (51 mm) keep the setup stable even with cameras or guiding accessories mounted.
The improved motors deliver high torque and can compensate for slight imbalance - ideal for heavier setups. The modular design makes the entire telescope easy to transport despite its observatory-level performance.
Application
The Celestron SC 235/2350 EdgeHD 925 AVX GoTo is the ideal choice for advanced observers and astrophotographers who want maximum image quality in a portable system.
What you can see with it:
- Detailed cloud bands and shadow transitions on Jupiter
- The Cassini separation, color bands and moons of Saturn
- Polar ice sheets and seasonal changes on Mars
- Bright deep-sky objects such as Orion Nebula, Trifid, M13
- Distant galaxies such as Sombrero, M81, M82 and Andromeda
- Ideal for planetary photography and deep-sky imaging with cameras such as the ZWO ASI533MC Pro or ASI2600MC Pro
The combination of long focal length and EdgeHD correction makes this system particularly suitable for high-resolution imaging of small objects, from the Moon to compact galaxies.
