Representing the mid-range aperture in the series and combining light-gathering power with ease of use, the Celestron CPC 925 GPS (XLT) 235mm f/10 Schmidt-Cassegrain GoTo Telescope
provides users with a complete rig for near- and deep-space observation
and astrophotography. Optically, it features a Schmidt-Cassegrain light
path consisting of a corrector plate, a spherical primary mirror, and a
secondary mirror. Complementing the optical system is the proprietary
StarBright XLT optical coating system that improves light transmission
and reflectivity across the entire visual spectrum. The combination of
optical components and the StarBright XLT system produces bright and
clear high-resolution images with true color rendition across the entire
field of view with minimal distortion, aberrations, or off-axis comas.
The
brain of the entire system is the NexStar+ computer controller.
Equipped with a database of over 40,000 objects, including the planets,
stars, nebulae, galaxies, and the complete Messier catalog, it can also
be programmed with up to 100 custom user-defined objects and have
filters added for custom object lists. Its intuitive menu-driven user
interface provides the power to observe the heavens with nine slew
speeds and three tracking rates, plus anti-backlash compensation and
Permanent Periodic Error Correction (PPEC) for smoother movements in the
motors and improved tracking over time. Features such as guided tours,
extended information on 200 popular objects, and multiple alignment
options make the NexStar+ controller easy to use and invaluable to new
users and experienced stargazers.
The optical tube is outfitted
with a standard 1.25" visual back to make it easier to find eyepieces,
accessories, and imaging gear. For visual observations, a 1.25" star
diagonal is included along with a 40mm Plössl eyepiece that yields 59x
magnification. The motorized dual-tine fork mount has dual-axis servo
motors that provide precision movements with minimal vibration and a
high resolution. It also has an integrated 16-channel GPS receiver that
sends information to the hand controller and requires limited input from
the user. A heavy-duty stainless steel tripod helps reduce vibrations
to ensure clear resolution during observation or imaging sessions.
