Ideal for astrophotography and visual observation

The Celestron CPC 925 GPS (XLT) is a 9.25" Schmidt-Cassegrain computerized telescope designed for visual infinity focus with 2" eyepieces. Its optimized baffle system minimizes vignetting at the edge of the field of view. The longer primary focal length and lower magnification secondary mirror contribute to a flatter field at the focal plane. StarBright XLT multi-coatings ensure maximum light transmission to the film plane.

Practical limits of the GPS interface

The telescope provides a 1.1 degree field of view and offers 33% more light gathering than the 8" model. It is compatible with computers and autoguiders for automated tracking. The system requires a power source for the GPS and computerized mount functions. Buyers who need a wider native field of view or a lighter instrument for portable use should consider other configurations.

Build quality and daily implications

The optical tube assembly measures 36.0 in x 16.0 in x 19.0 inches, requiring dedicated space for storage and transport. The fork arm mount integrates GPS alignment for faster setup under dark skies. Compatibility with Celestron's complete line of photographic and visual accessories allows flexible configuration. The design lineage traces back to the Ultima 9.25" introduced in 1995, reflecting mature mechanical engineering.

Questions about this item

Which aperture should I choose between the 8-inch and the 9.25-inch model?

The 9.25-inch optical tube gathers 33% more light than the 8-inch version, giving brighter deep-sky images and finer planetary detail.

What does the 1.1-degree field of view mean when I am at the eyepiece?

A 1.1-degree true field fits the full Moon with room to spare, making it easy to frame large nebulae or star clusters without a mosaic.

How does the Schmidt-Cassegrain design affect the focal plane for imaging?

The longer primary focal length and lower-power secondary produce a flatter field at the focal plane, reducing edge aberrations across a 2-inch sensor.
