Levenhuk Ra 2150N Dob Telescope is a Newtonian telescope with a focal length of 1215 mm (47.8 in) and an aperture of 150 mm (5.9 in). It is a perfect choice for amateur and experienced stargazers alike, as the optical tube is attached to a Dobsonian mount, which makes your journeys through the celestial sphere much easier. The Dobsonian mount is very easy to assemble - the kit already includes everything you will need to assemble it. All you need to do before your observations is set the assembled mount on the ground, attach the optical tube and lock it in place. The precision of the mount is guaranteed with manual azimuth and altitude slow-motion controls.

All optical elements, including the primary parabolic mirror, are made of high-quality BK-7 glass and the built-in cooling fan reduces the time it takes the optics to adapt to the outside temperatures.

Special roller bearings in the azimuth slow-motion control make azimuth adjustments even smoother. The telescope comes with a 1.25" dual-speed achromatic Crayford focuser, which provide for exceptional precision during focusing.

With the addition of the Plössl 9 mm eyepiece, the 150-mm (5.9-in) primary mirror of this telescope yields sharp and clear views of the lunar and planetary surfaces. The Plössl 25 mm eyepiece allows you to observe the wonders of the farthest reaches of the universe - with it, you can study star clusters, nebulae and galaxies that lie far beyond the Solar System.

The Dobsonian mount is shipped unassembled.
