Celestron NexStar 4SE Computerized Astronomical Telescope. USA Import
This Astonomy Telescope is ideal for a school or amateur enthusiast. Shipped from USA this telescope has rarely been used and has primarily stood as a decorative office feature.
NexStar SE Series ผสมผสานคุณสมบัติความคมชัดของกล้องหลอดส้มของ Celestron ในได้ผ่านการพิสูจน์มาจากอดีตให้เข้ากับเทคโนโลยีคอมพิวเตอร์ยุคใหม ระบบ Optics มากับเทคโนโลยีการเคลือบ StarBright XLT ช่วยให้แสงส่องผ่านได้มากขึ้น
Celestron’s NexStar 4 SE is the smallest and most portable telescope in Celestron’s NexStar SE series. Using a Maksutov-Cassegrain optical design, the NexStar 4 SE puts the magnifying power of a four-foot-long telescope into an optical tube only 13 inches long. The NexStar 4 SE features computerized finding and tracking of nearly 40,000 celestial objects, no-tool setup is easy, and planetarium software for your PC is included.
Celestron’s iconic “orange tube” design has several features to provide the best stargazing experience for beginners and experienced observers alike with 2.4-inch aperture provides excellent light-gathering ability.
You’ll get impressive views of the Moon and planets, along with deep sky objects like the Orion Nebula, while retaining a compact form factor.
It has a fully automated GoTo mount with database of 40,000+ celestial objects automatically locate and tracks objects for you. Using SkyAlign technology - your telescope aligned and ready to observe in minutes; Even if you’re unfamiliar with the night sky, you can easily align your telescope on any three bright object.
Unique single fork arm design and sturdy steel tripod all break down into separate components for easy transport and quick assembly; Alignment Procedures: SkyAlign, 1 Star Align, 2 Star Align, Auto 2 Star Align, Solar System Align, EQ North / EQ South Alignment (EQ align requires an equatorial wedge) Optical Tube Length:13.5 inch.
It also includes a sturdy adjustable tripod, a motorized alt-azimuth mount, and the NexStar hand held computer controller. You don’t need star charts or a GPS receiver to operate this telescope. Celestron’s "SkyAlign" procedure is easy to use, and experienced users will like the two-star align and solar-system align options because they are even quicker to set up.
