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 them can be observed in detail. You can also study the planets of the solar system. Up to Saturn, they are clearly visible. The telescope is suitable for beginners as well as experienced users. Due to its high image quality and ergonomic design, it will not disappoint even the most demanding astronomer.
The optics include an aluminum coated parabolic mirror
The optical design of the telescope is based on the primary mirror with a 153mm diameter. Since it features a paraboloid shape, even at the maximum useful magnification, optical distortions do not appear in the picture. The primary mirror has an aluminum coating with a reflectivity index of 92~96%. This produces high-contrast and vivid images of objects in the night sky. The Crayford Focuser enables you to obtain a maximally sharp image in any conditions.
Quick start kit
The kit includes two symmetrical eyepieces: 9mm and 25mm. They provide a good view and allow you to quickly start studying the starry sky. The search for astronomical objects is carried out using a 6x30mm optical finder.
