The Levenhuk Ra 200N Dobson telescope is a 200mm Newtonian reflector for observing deep sky objects, including star clusters, nebulae, and galaxies. You can also observe the planets of the solar system: Mars, Venus, Saturn, Jupiter, etc. as well as their satellites. A demanding user who wants a comprehensive observation experience will like this telescope. The telescope is easy to operate even for a beginner.
Parabolic primary mirror and active cooling of the optics
The primary mirror features a parabolic shape that minimizes optical distortion when observing at high magnifications. Its surface is covered with an aluminum coating with a reflectivity index of 92~96%. This has a positive effect on the contrast and brightness of the transmitted picture. You can adjust the focus with a dual-speed achromatic Crayford focuser. It is backlash-free and holds even heavy optical accessories securely for fast and accurate focusing.
The back cover of the telescope tube features a cooling fan. It makes the thermo stabilization of optics almost two times faster so that you can start observations much faster. The fan runs on batteries (purchased separately).
Dobsonian mount with an improved brake system side bearing for smooth tube movement
The telescope features a classic Dobsonian mount. It has a conventional design and all of the advantages of this mount type, but at the same time its mechanics has been significantly improved. A special brake system side bearing for smooth tube movement allows you to move the optical tube a few centimeters up or down. When using additional attachments, this will quickly balance the telescope and maximize stability.
There are scales on the mount sides for convenient balancing. In addition, the bearings are durable and provide a smoother movement, which is important when using the telescope at high magnifications.
