Outfitted with a large aperture, long effective focal length, and their proprietary StarBright XLT optical coatings, the Celestron CGX 925 Schmidt-Cassegrain GoTo Telescopeprovides 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.

2350mm Focal Length    StarBright XLT Optical Coating System    25mm Eyepiece & 6x30 Finderscope

• 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

• 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

• 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

Q: 7. can this zoom in on closer objects, such as jets or ufo's?

A: The Celestron NexStar 6SE 150mm f/10 Schmidt-Cassegrain GoTo Telescope can focus as close as 20 feet away from the telescope so if can be used to view closer objects such as airplanes. However, a spotting scope would be better suited for such activities. Spotting scopes are lighter and used on standard tripods with faster movement.

Q: 8. Will this OTA fit on a Nexstar Evolution Mount?

A: The Celestron EdgeHD CGE 8" f/10 Aplanatic Schmidt-Cassegrain Telescope (OTA Only) BH #CEEDGEHD800 • MFR #91030-XLT weight is 14 lbs. It can be supported by the Nexstar Evolution Mount.

Q: 9. Is the dovetail compatible with an Orion Starseeker IV mount?

A: The Celestron C6-A-XLT CG-5 6" f/10 Schmidt-Cassegrain Telescope has a standard Vixen dovetail rail so it will fit any brand mount that uses a Vixen dovetail. We do not sell Orion brand mounts but based on the specs on Orion's website, the Celestron telescope not will fit. Plus the Orion mount only supports 13 pounds. The Celestron scope weighs 10. I would recommend using a stronger mount for the Celestron such at this scope and mount kit: https://bhpho.to/2YyNBqG

Q: 10. Would this set up be capable of nebulas/galaxies as well as some planets for astrophotograhpy?

A: Yes the Celestron EdgeHD CGE 8" f/10 Aplanatic Schmidt-Cassegrain GoTo EQ Telescope is capable of viewing planets, nebulae and galaxies. It is also suitable for use in astrophotography when used with a camera.
