Levenhuk Ra 250N Dobson Telescope Product description

  1. Reflector Telescope: The Levenhuk Ra 250N Dobson is a Newtonian reflector telescope on a Dobsonian mount. This design utilizes a parabolic primary mirror to gather and focus light, making it exceptionally effective for observing faint deep-sky objects such as nebulae, galaxies, and star clusters, thanks to its large light-gathering capacity. It also offers crisp views of the Moon and planets without chromatic aberration.

  2. Large Aperture for Deep-Sky Views: Equipped with a substantial 250mm (10-inch) aperture, this telescope excels in collecting vast amounts of light. This feature is crucial for revealing intricate details and subtle structures in distant astronomical phenomena, providing significantly brighter and more resolved images compared to smaller instruments. It allows stargazers to explore the universe in remarkable detail.

  3. Intuitive Dobsonian Mount: The telescope is mounted on a sturdy and user-friendly Dobsonian alt-azimuth base. This type of mount is renowned for its simplicity, stability, and smooth operation, enabling effortless manual tracking of celestial objects across the night sky. Its robust construction ensures minimal vibrations, providing a steady platform for high-magnification observations.

  4. High-Quality Optics and Construction: Featuring a highly reflective parabolic primary mirror, the Levenhuk Ra 250N delivers sharp, high-contrast images with excellent detail. The optical tube is crafted from durable metal, while the Dobsonian base is constructed from sturdy wood, ensuring both longevity and stability during use. The 2-inch Crayford focuser provides smooth and precise focusing.
