Celestron NexStar 8SE Computerized Telescope
The Celestron NexStar 8SE combines the iconic "orange tube" heritage with updated optical and computerized features. Featuring a large 203.2mm (8-inch) Schmidt-Cassegrain optical tube paired with StarBright XLT high-transmission coatings, the 8SE delivers exceptional light-gathering capability for observing the Moon, planets, and faint deep-sky targets like the Whirlpool Galaxy and Hercules Globular Cluster. Equipped with an automated GoTo single fork arm mount, SkyAlign technology, and a 40,000+ object NexStar+ database, it offers an intuitive stargazing experience for both beginners and advanced observers.
(Solar Warning: Never look directly at the Sun or use the telescope without a certified solar filter. Permanent and irreversible eye damage or equipment damage may occur.)
【Key Features & Technical Highlights】
8-Inch Aperture SCT Optics: 203.2mm aperture with StarBright XLT coatings provides $843\times$ the light-gathering power of the human eye for sharp, high-contrast planetary and deep-sky views.
SkyAlign Technology: Fast alignment method allows setup in minutes by centering any three bright celestial objects without prior knowledge of the night sky.
Patented Single Fork Arm Mount: Portable computerized Alt-Az mount breaks down into lightweight components for easy transport and quick assembly.
NexStar+ Hand Control: Database with over 40,000 celestial targets, featuring automatic tracking, Sky Tour modes, and programmable tracking rates (Sidereal, Solar, Lunar).
System Expandability: Fastar-compatible optical design for versatile astroimaging; supports add-on accessories such as the SkyPortal Wi-Fi module, SkySync GPS, StarSense AutoAlign, and planetary cameras.
