The Celestron CPC Deluxe 925 HD Computerized Telescope is a complete observation and astroimaging rig composed of a powerful and portable optical tube, a sturdy dual fork mount, the iconic NexStar computer hand controller, and a solid stainless steel tripod. A suite of accessories let you start enjoying the night sky right out of the box.
Celestron CPC Deluxe 925 HD 9.25" f/10 Cassegrain Optical Tube Assembly
The Celestron CPC Deluxe 925 HD Computerized Telescope is outfitted with an aperture that balances power and portability, offering you an OTA that can resolve dim deep-sky objects and still be handled by one person. It features the proprietary aplanatic catadioptric-style Edge HD optical system consisting of a corrector plate, a spherical primary mirror, and a secondary mirror along with a set of field-flattening lenses integrated into the baffle tube. Complementing the EdgeHD system is the proprietary StarBright XLT optical coating system that improves light transmission and reflectivity across the entire visual spectrum. The combination of EdgeHD and StarBright XLT produces bright and clear high-resolution images with true color rendition across the entire field of view without distortion, aberrations, or off-axis comas.
Optics
- 9.25" (235mm) f/10 aperture strikes a balance between power and portability
- 2350mm effective focal length
- EdgeHD catadioptric optical system employs an aplanatic field-flattener design that eliminates spherical aberration, field curvature, and off-axis star coma to improve resolution, sharpness, and clarity across the entire field of view–especially at the edges
- Fine-annealed Pyrex glass reduces internal light loss to improve color, clarity, and sharpness
- StarBright XLT optical coatings
- Flexible tension clutches hold the primary mirror in place to reduce image shift without putting any force or pressure on the mirror assembly, keeping subjects centered
- Internal mirror locks prevent accidental adjustment to focus, which is important during long-exposure astrophotography
- Internal focusing mechanism moves the primary mirror forward and back to achieve tack-sharp views
- Resolution: 0.59 arcsec (Rayleigh); 0.49 arcsec (Dawes)
- Secondary mirror obstruction: 3.35" (85mm); 36% by diameter; 13% by area
- Fastar compatibility allows you to remove the secondary mirror and replace it with an imaging system to greatly reduce the focal ratio for shorter exposure times and a wider field of view
StarBright XLT System
- Maximizes light transmission through optical path
- Improves color rendition, contrast, sharpness, resolution, and brightness
- Broadband system provides flat wavelength transmission across the entire visual spectrum
- Multilayer mirror coatings with layers of aluminum, SiO2 (quartz), and TiO2 (titanium dioxide)
- Multilayer 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
Included Accessories
Eyepiece:
- 2" barrel diameter
- Accepts most 2" astronomical filters
- 23mm focal length produces 102x power
Diagonal:
- 90° angle places head in comfortable viewing position
- 2" snout and holder
- Star configuration corrects view horizontally but not vertically
- 2-to-1.25" reducer adapter allows the use of smaller eyepieces and accessories with the included visual back and diagonal
Finderscope:
- Low 9x magnification ensures a wide field of view for easier alignment
- 50mm objective allows users to see dimmer objects to have more alignment star choices
- Includes quick release bracket
The Celestron Heavy Duty for CPC, Nextar GPS is a full size, aluminum tripod with adjustable legs designed to provide great stability for your telescope. It comes with a metal accessory tray and eyepiece storage capability. This tripod features mounting holes for alt-az mounting and is also suitable to be used with a wedge.
