Striking a comfortable balance between power and portability, the Celestron Advanced VX 6" f/10 GoTo EQ Telescopeis an ideal choice for observing objects within or beyond our solar system. It features a Schmidt-Cassegrain optical system consisting of a corrector plate, spherical primary mirror, and secondary mirror that work together to reduce spherical and chromatic aberrations for crisp and clear high-resolution images with accurate color representation without distortion, especially at the edges. Complementing the optical system is the proprietary StarBright XLT optical coating system, which improves light transmission and reflectivity across the entire visual spectrum.

The optical tube is outfitted with a standard 1.25" visual back to make it easier to find eyepieces, accessories, and imaging gear. For visual observations, a 1.25" star diagonal is included along with a 25mm eyepiece that yields 60x magnification. The C6-A-XLT is offered here without a mount or tripod for users who already have a reliable support system and are looking to upgrade or add to their existing gear, but comes with a standard-sized CG-5 dovetail plate that is compatible with Vixen-style saddles.

• Schmidt-Cassegrain catadioptric optical design
• StarBright XLT optical coatings
• Resolution: 0.93 arcsec (Rayleigh); 0.77 arcsec (Dawes)
• Secondary mirror obstruction: 2.2" (69mm); 37% by diameter; 14% by area

• 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
• 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 assembly (OTA) only, mount and tripod required for proper use
• Standard CG-5 (Vixen-style) dovetail plate for compatible saddles
• OTA weight: 10 pounds

• Use for prime focus or projection astrophotography with optional adapters

• Eyepiece:
• 1.25"-diameter barrel
• Accepts most 1.25" eyepiece filters
• 25mm focal length yields 60x power
• 0.83° apparent angle of view
• 44' field of view at 1000 yards

• Diagonal:
• 90° angle puts head in comfortable viewing position
• Threaded for direct connection to OTA without the need for the visual back
• 1.25" snout and eyepiece/accessory holder
• Star diagonal corrects image horizontally, but not vertically

• Finderscope:
• Low 6x magnification preserves wide field of view to more easily find alignment or guide stars
• 30mm aperture helps to see dimmer objects and stars for easier alignment and star-hopping navigation

Related Questions and Answers

Q: 1. I see the mount handle obstructing the polar bore scope ? how do you polar align this with handle obstructing ?

A: The CGX and CGX-L mounts utilize the All Star Polar Alignment routine. It is substantially more accurate than a polar finder scope. However, if a customer insists on using a Polar Scope, we do offer one that is used off axis. But trust me, once you use All Star Polar Alignment - you will never want to use a polar scope again.

Q: 2. Does the Celestron Illuminated RACI Finder Scope fit on the 9.25 OTA?

A: Yes, the Celestron C9 1/4-A XLT 9.25" f/10 Schmidt-Cassegrain Telescope (OTA Only, CGEM Dovetail) is compatible with the Celestron RACI finder scope: https://bit.ly/3HnwhMC

Q: 3. Does it need a second counterweight to do astrophotography with a dslr maybe an autotracker?

A: It depends on the weight of your camera body. If your camera body is over 2 lbs. I would suggest additional counter balance weights.

Q: 4. 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.
