Celestron

Striking a comfortable balance between power and portability, the Celestron C6-A-XLT CG-5 6" f/10 Schmidt-Cassegrain Telescope is 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.Optical Tube 6" (150mm) aperturef/10 focal ratio1500mm effective focal lengthSchmidt-Cassegrain catadioptric optical designStarBright XLT optical coatingsResolution: 0.93 arcsec (Rayleigh); 0.77 arcsec (Dawes)Secondary mirror obstruction: 2.2" (69mm); 37% by diameter; 14% by areaStarBright XLT System Maximizes light transmission through optical pathImproves color rendition, contrast, sharpness, resolution, and brightnessBroadband system provides flat wavelength transmission across the entire visual spectrumMulti-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 titaniumHigh-transmission water white glass corrector plate limits light loss due to internal absorptionMounting Optical tube assembly (OTA) only, mount and tripod required for proper useStandard CG-5 (Vixen-style) dovetail plate for compatible saddlesOTA weight: 10 poundsIncluded Accessories Visual back:Standard Schmidt-Cassegrain telescope threads1.25" eyepiece/accessory holderUse for prime focus or projection astrophotography with optional adaptersEyepiece:1.25"-diameter barrelAccepts most 1.25" eyepiece filters25mm focal length yields 60x power0.83 apparent angle of view44' field of view at 1000 yardsDiagonal:90 angle puts head in comfortable viewing positionThreaded for direct connection to OTA without the need for the visual back1.25" snout and eyepiece/accessory holderStar diagonal corrects image horizontally, but not verticallyFinderscope:Low 6x magnification preserves wide field of view to more easily find alignment or guide stars30mm aperture helps to see dimmer objects and stars for easier alignment and star-hopping navigation
