Celestron C8-A XLT (CGE) Optical Tube Assembly Product Info Now you can have your own a la carte assemblage of your preferred optical tube and mount. All Celestron Schmidt-Cassegrain telescopes utilize the multicoated Starbright® coatings group. Highly reflective coatings are used on the mirrors, with anti-reflective coatings employed on the correcting lens for increases in light transmission. Celestron's optical systems internal baffling ensures the highest contrast levels. To maintain the company's mindset as well as to provide consistently high performance and customer satisfaction, all Celestron Schmidt-Cassegrain optical assemblies utilize the same superior optics regardless of their size or configuration. The StarBright XLT coatings are all that distinguish this offering from the ordinary 8" optical tube assembly. These coatings dramatically decrease the total percentage of light loss incurred by the scope's system of lenses & mirrors by a measure of 43%! Light is invariably lost as it passes through lenses or is reflected from mirrors, and this can have a particularly dramatic effect of deep space objects. StarBright XLT coatings are a highly intensive process which diminishes this effect and brings the faintest things your scope can resolve into greater detail. They'll bring the details of bigger apertures without adding to the weight of your rig. Features: 8" Schmidt-Cassegrain Optical Tube Assembly Aluminum Optical Tube Celestron's premium StarBright XLT coatings mm focal length (f/ mm eyepiece included (81x) Visual back allows for use with 1.25" accessories 6x30 finderscope to help accurately find objects Star diagonal provides more comfortable viewing position when observing objects that are high in the sky Includes dovetail rail compatible with CGE mount Specifications: Optical Design Schmidt-Cassegrain Aperture (mm) mm (8 in) Focal Length mm (80 in) Focal Ratio 10 Focal Length of Eyepiece 1 (mm) 25 mm (0.98 in) Magnification of Eyepiece 1 81 x Finderscope 6x30 Star Diagonal 1.25 Optical Tube Aluminum Highest Useful Magnification 480 x Lowest Useful Magnification 29 x Limiting Stellar Magnitude 14 Resolution (Rayleigh) 0.69 arc seconds Resolution (Dawes) 0.57 arc seconds Light Gathering Power (Compared to human eye) 843 x Secondary Mirror Obstruction 2.5 in (64 mm) Secondary Mirror Obstruction by Diameter 31 % Secondary Mirror Obstruction by Area 9.77 % Optical Coatings StarBright XLT Optical Tube Length 17 in (432 mm) Optical Tube Weight 12.5 lbs (5.67 kg) Dovetail Compatibility CGE Mount Package Contents: Celestron C8-A XLT (CGE) Optical Tube Assembly

Vortex Spotting Scope - Razor HD 11-33-x50 The Vortex Spotting Scope - Razor HD 11-33-x50 features high-quality glass with specialized optical coatings to provide clear and bright images. The triplet apochromatic lens elements are made of High Density (HD) Extra-low Dispersion (ED) glass to increase light transmission, minimize distortion and virtually eliminate chromatic aberration. All air-to-glass surfaces have Vortex's XR anti-reflective coatings to minimize light loss. Additionally, they are ArmorTek coated for scratch resistance. To ensure accurate color across the entire visible spectrum, the Porro prisms are dielectric coated. These coatings are highly reflective and lose less than 1% of the light that passes through them. The use of Porro prisms creates a better depth of view over roof prisms. This combination of coatings and optics creates a spotting scope that produces bright, clear, highly contrasted images with accurate color transmission. The lightweight magnesium-alloy body is o-ring sealed and argon-filled to be water and fogproof. A dual focus system features a coarse fast-focus and a fine-focus wheel. The scope has a tripod mounting shoe that also accepts a ¼"-20 mounting bolt. For comfort and convenience, the tripod collar rotates to permit it the eyepiece to be put in the best viewing position. A retractable lens shade keeps the Sun or rain off the objective lens. Features Optical Performance 11-33x zoom eyepiece 50mm objective lens High Density (HD) Extra-low Dispersion (ED) glass Triplet apochromatic lens eliminates chromatic abberation Porro prism design for better depth of view Highty reflective dielectric multicoatings on prisms Vortex XR anti-reflective lens coatings ArmorTek scratch-resistant exterior lens coatings Use and Handling Straight view eyepiece for easier subject acquisition and digiscoping Dual focusing dials offer rapid rough and fine-focus Twist-up eyecup Rotating tripod ring &frac;"-20 threaded mount for tripods Construction Details Magnesium alloy body O-ring sealed to be waterproof Argon-filled to be fogproof Built-in retractable sunshield Specifications Magnification: 11-33x Objective Lens Diameter: 50 mm Focal Length: Not Specified by Manufacturer Field of View: Angular: 3.6 - 1.8°, Linear: 191 - 96' @ 1000 yd (63.5 - 31.9 m @ 1000 m) Minimum Focus Distance: 6.6' (2 m) Exit Pupil Diameter: 4.6 - 1.5 mm Eye Relief: 20 mm Filter Thread: Not Specified by Manufacturer Mounting Thread: ¼"-20 Weatherproofing: Waterproof, o-ring sealed Dimensions: (Diam. x L) 2.0 x 11.0" (5.0 x 28.0 cm) Weight: 1.6 lb (709 g)

The Celestron Telescope Astrofi 130 f/5 Reflector Telescope utilizes an integrated antenna to emit a local Wi-Fi signal so you can control the mount via Android and iOS smartphones and tablets running their free SkyPortal app. Optically, the Celestron Astrofi 130 sports a large 130mm aperture and a short 650mm focal length to produce a fast focal ratio that can resolve deep sky objects that smaller refractor-style scopes cannot, such as splitting binary stars or separating star clusters.With highly-reflective aluminum and SiO2 (quartz) mirror coatings, light loss is limited so you can make detailed observations of the Moon, view planets and distant nebulae, and get great wide-field views of the sky for comet watching and asteroid hunting. This complete observation rig includes the optical tube assembly, a motorized mount, an aluminum tripod, two eyepieces, and a red-dot finder.The OTA is mounted on a single-arm motorized alt-az mount.Guiding the mount is the SkyPortal app. Packed with over 120,000 objects it is designed to help users set up quickly and start observing faster. The app offers align aids, can automatically find objects in the night sky; and even offers guided tours of the most interesting objects overhead on any given night.The mount of the Celestron Telescope Astrofi 130 runs on eight user-supplied AA batteries, and the entire rig assembles and breaks down without the need for tools so set up is easy and you can start observing sooner.
