The Dobson telescope Levenhuk Ra 250N Dob is a Newton's reflector with a mirror diameter of 250 mm. It can observe binary stars, nebulae, galaxies, star clusters and many other objects in outer space. It is possible to consider practically all objects of the NGC catalog, and many of them in details. Near space is available for observations: the Moon, Mars, Jupiter, Saturn, and even Neptune and Pluto, as well as some of their moons. At the same time, the telescope is quite easy to operate, so it is suitable even for a beginner, astronomy.
Reflector with a parabolic mirror with a diameter of 250 mm
Optical distortion is not detected even if you use all the features of optics. The mirror is supplemented with an aluminum coating with a reflection coefficient of 92-96%. The telescope is equipped with a two-speed Crayford focusor, which provides smooth and backlash-free sharpness.
Active cooling of the optics accelerates thermal stabilization It is needed to accelerate thermal stabilization and runs on batteries (not included). The need for thermal stabilization arises when the telescope is taken out of a warm room outdoors: the mirror must "cool" so that there is no thermal distortion in the picture. Active cooling significantly speeds up this process. Dobson mounting is one of the most convenient and easy to learn, it is ideal for long-term observations. Moreover, in the Levenhuk Ra 250N Dob telescope, it is improved by a system of high-altitude bearings and balancing.
High-altitude bearing and balancing system To better balance the optical tube, it can be moved a couple of inches up or down. There are scales on the mounting sides to help balance. This feature will come in handy when using heavy glasses or an additional finder. The bearings themselves have become more reliable, so they are less prone to wear during operation.
All necessary observations are already included. This accessory will allow you to quickly start observations. fast and accurate guidance without much effort
The system of high-altitude bearings and balancing - high smoothness of movement of a pipe.
