The Levenhuk Ra 150N Dobson telescope is an easy-to-use optical instrument for observing deep-sky objects, including bright and faint galaxies, star clusters, and nebulae. Some of these can be observed in detail. You can also explore the planets of the Solar System, which are visible up to Saturn. The telescope is suitable for both beginners and experienced users. Thanks to its high image quality and ergonomic design, it will not disappoint even the most demanding astronomers.

Its optics include a parabolic mirror with an aluminum coating. The optical design of the telescope is based on a primary mirror with a diameter of 153 millimeters. Because it is parabolic in shape, no optical distortions are observed in the image, even at the maximum useful magnification. The primary mirror has an aluminum coating with a reflectivity of 92–96%, providing vivid, high-contrast images of objects in the night sky. The dual-speed Crayford focuser allows you to achieve the sharpest image under any conditions.

Quick Start

The package includes two symmetrical optical eyepieces: 9 mm and 25 mm. They provide a good field of view and allow you to quickly start exploring the starry sky. Astronomical objects are located using a 6x30 mm optical finderscope.
