Celestron Advanced VX 235/2350 Schmidt-Cassegrain Telescope (C9.25)
Celestron Advanced VX 235/2350 (C9.25) combines high-contrast Schmidt-Cassegrain optics with the computerized Advanced VX equatorial mount designed for visual astronomy and astrophotography. The telescope delivers a long 2350 mm focal length in a compact optical tube assembly, making it suitable for planetary observation, deep-sky imaging, and mobile astrophotography.
Key advantages
- Compact Schmidt-Cassegrain optical system with long focal length
- StarBright XLT multi-coating for improved light transmission and contrast
- Main mirror focusing system with pre-loaded ball bearings to reduce mirror shift
- Advanced VX equatorial mount optimized for astrophotography
- PEC correction for reduced periodic tracking error during long exposures
- 40,000-object GoTo database
- Compatible with Vixen and Celestron CGE dovetail rails
- High-torque servo motors for improved tracking stability
- NexStar+ and Celestron PWI support
- Suitable for Moon, planetary, nebula, and galaxy observation
Product description
The Celestron Schmidt-Cassegrain optical design combines a long focal length with a compact optical tube. Light passes through an aspherically figured Schmidt corrector plate, reflects from the spherical primary mirror to the secondary mirror, and then back through the central opening of the primary mirror into the focuser.
The closed optical tube design minimizes internal air turbulence and helps protect the optics from dust. The StarBright XLT multi-coating improves brightness and reduces stray light reflections.
The C9.25 optical tube is known for particularly high contrast among Schmidt-Cassegrain models due to its longer optical tube design. The telescope is suitable for visual observation and astrophotography, with an extensive range of compatible accessories available.
The main mirror focusing system provides a large focusing range for use with various accessories. Pre-loaded ball bearings help minimize mirror shift during focusing.
The Advanced VX equatorial mount is designed for mobile astrophotography with telescopes up to 14 kg. PEC correction reduces periodic tracking errors commonly associated with worm gear systems, allowing longer exposure astrophotography.
The mount allows tracking objects well beyond the meridian without immediate tube reversal. A wider mount base increases stability under heavier loads, while improved high-torque motors compensate for minor balancing inaccuracies.
