The Celestron CPC Deluxe 925 HD 9.25" f/10 Cassegrain Optical Tube Assembly 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.

• 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

• 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

Eyepiece:

• 2" barrel diameter
• Accepts most 2" astronomical filters
• 23mm focal length produces 102x power

• 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

• 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

A: A2" powermate & 2" 2.2lb Televue eye piece + AutoGuider should be no problem for the mount or the tripod

Q: 10. Will this mount to a Celestron Advance-vx tripod? Also would Celestron wedge mount on that tripod.

A: No, the Celestron Heavy Duty Tripod for CPC, Nextar GPS will not mount on the Celestron Advanced VX Tripod, as that tripod does not have the correct mount for it. One can mount this on the Celestron Heavy Duty Tripod for CPC, Nextar GPS, BH #CEHDT (https://bhpho.to/3M6Bps2). One could also mount the the Celestron HD Pro Wedge on this tripod, BH #CEHDPW (https://bhpho.to/40M49dQ).
