Celestron Schmidt-Cassegrain telescope SC 235/2350 CGX 925 GoTo (52296)

Despite its long focal length, the optical tube assembly (OTA) of this telescope is remarkably short, making it compact and easy to transport. The design ensures excellent image quality, high contrast, and versatility for various applications. Here's how it works:

Light first passes through an aspherically figured Schmidt corrector plate, then reflects off a spherical main mirror. This light is redirected to a secondary mirror, which sends it back through a central hole in the main mirror to the focuser at the bottom of the OTA. The closed system prevents air turbulence and protects against dust. The Schmidt plate is multi-coated to enhance brightness and reduce stray light reflections.

This telescope provides exceptional image quality, making it ideal for planetary observation. Its Schmidt-Cassegrain design also supports astrophotography and occasional terrestrial use, such as birdwatching. With an aperture ratio of 1:10, it is well-suited for capturing detailed celestial images. The main mirror focusing mechanism offers a wide focus range, accommodating various accessories. High-quality materials like CNC-milled aluminum and stainless steel ensure durability while keeping the weight low, eliminating the need for a heavy mount.

Key Features of the Optics:

• Long focal length with a short OTA

• Lightweight aluminum construction

• High-quality XLT multi-coating

• Closed system for dust protection

• Pre-loaded ball bearings to minimize mirror shift

CGX Equatorial Mount and Tripod

The CGX mount represents a significant upgrade in design and performance, catering to both visual observers and astro-imagers. It incorporates advanced features for improved stability, ease of use, and remote operation.

Mount Features:

• Sturdier and more rigid design with faster vibration dampening

• Enhanced motors for better torque, slewing, and tracking under heavy loads

• Heavy-duty belt-drive system to minimize backlash

• Spring-loaded brass worm wheel and stainless steel worm gear for smooth operation

• Internal cabling to prevent snags during remote operation

• Home sensors for consistent starting positions after power resets

• Limit sensors to prevent over-slewing or tracking beyond safe limits

• Adjustable EQ head for optimal center-of-gravity alignment (latitude range: 3°–65°)

• Dual-fit saddle compatible with CG-5/Vixen and CGE/Losmandy dovetails

Tripod Features:

• 2" steel legs with height index marks for quick leveling

• Accessory tray for eyepieces, smartphones, or other tools

• Collapsible legs with the tray installed for faster setup

Electronics:

• NexStar+ hand control with USB port

• Two AUX accessory ports for wireless/WiFi modules (sold separately)

• USB 2.0 port for direct PC connection

• Autoguider port and PPEC readiness

• Internal real-time clock to save time/location data

The CGX mount is designed for both visual observation and astrophotography. It features ergonomic improvements, better cable management, and a lower-profile EQ head for increased stability.
