The Celestron CPC Deluxe 800 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 be handled by one person. It features the proprietary aplanatic catadioptric-style Edge HD optical system and the 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. The dual-fork-arm alt-az motorized mount features the simple SkyAlign setup and a NexStar controller with a database of more than 40,000 celestial objects.
Optics
- 8" (203.2mm) f/10 aperture strikes a balance between power and portability
- 2032mm 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: 0.69 arcsec (Rayleigh); 0.579 arcsec (Dawes)
- Secondary mirror obstruction: 2.5" (64mm); 31% by diameter; 9.77% 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
Mount
- Dual-fork alt-az
- NexStar+ database: more than 40,000 objects, 100 user defined programmable objects, enhanced information on over 200 objects
- DC servo motors
- 2 AUX Ports (Hand controller can use any of the AUX ports)
- 12V 1.5A power supply
