Preces apraksts

Preces apraksts

Levenhuk Ra 250N Dob is a Newtonian reflector with a 250mm diameter primary mirror. Its optics allow for observing thousands of deep-sky objects in detail that cannot be observed with small-aperture telescopes. You can also use this telescope for outer space exploration. For example, you can observe small structures on Mars’s surface, details in the atmosphere of Jupiter, the Encke gap within Saturn’s rings, and even a satellite of Neptune, Triton. It is an excellent optical instrument for visual observations of space that is best suited for trips to the countryside. Parabolic primary mirror with active cooling of the optics The parabolic primary mirror creates a clear image free from optical distortion, even at extreme magnification. Its surface is covered with an aluminum coating that reflects 92~96% of light improving image quality. Due to the dual-speed Crayford Focuser, the focus can be smoothly adjusted. The primary mirror features a cooling system that runs on batteries (purchased separately). If any telescope is moved from a warm room to a cold street and vice versa, the optics will take several hours to “cool down”. The built-in fan speeds up temperature stabilization almost twofold. Stable and reliable Dobsonian mount with a brake system side bearing for smooth tube movement The Dobsonian mount is easy to assemble and handle. It reliably holds the optical tube and allows you to carry out long-term observations with maximum comfort. The mount mechanics has been improved. Now, the movement of the tube is smooth so that tracking objects at high magnification is much more comfortable. A special brake system side bearing for smooth tube movement allows you to move the optical tube a few centimeters up or down. There are scales on the mount sides for convenient balancing. In addition, the bearings have a more robust design (compared to conventional ones), and so they will run smoothly throughout their entire service life. Quick start kit The telescope kit includes base accessories that allow you to start observations right away. 9mm and 30mm eyepieces are ideal for your first introduction to deep space. An 8x50mm optical finder is used to search for objects. Features:
