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 objects can be observed in detail. It is also possible to study the planets of the Solar System. Up to Saturn, they are clearly visible. The telescope is suitable for both beginners and more experienced users. Thanks to the high image quality and its ergonomic design, it will not disappoint even the most demanding amateur astronomers.
The optical system includes a parabolic mirror coated with aluminum
The optical scheme of the telescope is based on a primary mirror with a diameter of 153 mm. Due to its parabolic shape, the reproduced image does not show optical distortions even at the highest magnifications. The primary mirror is equipped with an aluminum coating with a reflection coefficient of 92~96%. It therefore produces vivid images with high contrast of objects visible in the night sky. The dual-speed Crayford focuser allows you to achieve the sharpest images under any condition.
Ready-to-use kit
The kit includes two symmetrical eyepieces: 9 mm and 25 mm. These eyepieces offer a great view and allow you to start immediately exploring the starry sky. The search for astronomical objects is entrusted to a 6x30 mm optical finder.
