The CGX Equatorial 925 9.25" f/10 Schmidt-Cassegrain GoTo Telescope features Celestron's premium StarBright XLT coated optics and the CGX computerized equatorial mount. The CGX 925 offers the middle ground for those looking to combine portability with high resolution. This telescope is especially at home as a solid platform for long-exposure photography with optional CCD cameras or photographic equipment. With over 9" of aperture and Celestron's premium StarBright XLT coatings, the CGX 925 gives you over 1000 times more light gathering power than the unaided eye.
Celestron C9 1/4-A XLT 9.25" f/10 Schmidt-Cassegrain Telescope (OTA Only, CGEM Dovetail)
Outfitted with a large aperture, long effective focal length, and their proprietary StarBright XLT optical coatings, the Celestron C9 1/4-A XLT 9.25" f/10 Schmidt-Cassegrain Telescope provides power and portability. The coating system consists of anti-reflection coatings on the corrector plate, highly reflective index mirror coatings, and low-absorption/high-transmission glass components to ensure that the maximum amount of light is gathered and transmitted to your eye. This system ensures bright and clear high-contrast images with accurate color rendition across the entire visual spectrum without visible distortion at the edges. Celestron includes a standard 1.25" visual back to accept eyepieces and accessories such as the 25mm eyepiece and 90° diagonal supplied with the optical tube assembly (OTA). This OTA is offered here without a mount or tripod for users who already have a support system. Just ensure the mount's payload capacity exceeds 20 pounds to safely carry the weight and that the mount has a Losmandy-style saddle to match the OTA's CGEM mounting plate.
Optical Tube
- 9.25" (235mm) aperture
- f/10 focal ratio
- 2350mm effective focal length
- Schmidt-Cassegrain design optical path
- StarBright XLT optical coatings
- Resolution: 0.59 arcsec (Rayleigh); 0.49 arcsec (Dawes)
- Secondary mirror obstruction: 3.35" (85mm); 36% by diameter; 13% by area
StarBright XLT System
- Maximizes light transmission through the optical path
- Improves color rendition, contrast, sharpness, resolution, and brightness
- Broadband system provides flat wavelength transmission across the entire visual spectrum
- Multi-layer mirror coatings with layers of aluminum, SiO2 (quartz), and TiO2 (titanium dioxide)
- Multi-layer anti-reflective corrector plate coatings with layers of MgF2 (magnesium fluoride) and HfO2 (hafnium dioxide); hafnium has a wider band-pass than the commonly used titanium
- High-transmission water white glass corrector plate limits light loss due to internal absorption
Mounting
- Optical tube only; a mount and tripod are required for proper use
- Comes with an attached CGEM dovetail plate, which is compatible with all Celestron and select third-party saddles; the plate can be unscrewed
- Mount must have a payload capacity of over 20 lb to safely support the OTA
