Explore Scientific Ultra Light Dobsonian 254 mm Product description

  1. Generous Aperture: The 254 mm (10-inch) primary mirror provides significant light-gathering capability, making it an excellent choice for observing faint deep-sky objects such as galaxies, nebulae, and star clusters. Its wide field of view also excels at sweeping through broad celestial landscapes.

  2. Dobsonian Reflector Design: This telescope is a Dobsonian Reflector, characterized by its parabolic primary mirror and intuitive, alt-azimuth mount. This straightforward design prioritizes large aperture for maximum light collection, offering superb views and ease of use, particularly for visual astronomy without complex setup.

  3. Ultra Lightweight and Portable: Despite its large aperture, the innovative truss-tube design significantly reduces weight and allows the optical tube to be disassembled into compact sections. This makes the Explore Scientific Ultra Light Dobsonian remarkably portable for a 10-inch telescope, ideal for transport to dark sky sites.

  4. Precision Focuser: Equipped with a 2-inch Hexafoc Dual-Speed Focuser, this telescope provides smooth and precise focusing, essential for sharp planetary views and detailed observations. The dual-speed mechanism allows for coarse and fine adjustments, ensuring optimal clarity for both high and low magnifications.

ABOUT THE Explore Scientific Ultra Light Dobsonian 254 mm

The Explore Scientific Ultra Light Dobsonian 254 mm stands out in its series by combining a substantial 10-inch aperture with an innovative ultra-lightweight, collapsible truss-tube design. This makes it an incredibly versatile instrument, offering the impressive light-gathering power typically found in larger, more cumbersome telescopes, but in a highly portable package. It is a reflector telescope, specifically a Dobsonian, meaning it utilizes mirrors to gather and focus light, mounted on a simple, intuitive alt-azimuth base for manual tracking. This construction is ideal for observers who prioritize visual astronomy and seek maximum aperture for deep-sky objects without the complexity of equatorial mounts. Crafted from lightweight aluminum and steel, it provides robustness without sacrificing mobility. Its primary function is to deliver bright, detailed views of nebulae, star clusters, galaxies, and planetary surfaces, making it perfect for both backyard observers and those who travel to darker skies.
