Levenhuk Sky Matic Reflector Telescope is an astronomer's dream. The Levenhuk SkyMatic 135 GTA Telescope is a reflector on an azimuth mount with GoTo function. This large aperture (f/5) telescope is not only suitable for astronomical observations, but also for astrophotography. Lunar craters with a diameter of just 4.5 miles, the rings of Saturn, the seasons change on Mars, and the distant nebulae and galaxies: can all be observed in detail through this telescope. You can also watch the most striking objects from the Messier and NGC catalogues, asteroids, comets, and more. Maximum useful magnification in the telescope is 260x with the resolution of 0.92". Such a combination ensures the highest HD picture quality with magnification, suitable for most astronomical observations. Two achromatic eyepieces SUPER 10 and SUPER 25 with a 31.75-millimeter (1.25-inch) diameter are included in the package and serve as powerful image correction tools. The optics used in the eyepiece are glass with a special coating. Field of view is 50-52 degrees. The telescope comes with an azimuth AZ 114 GT SynScan computer-guided mount. Thanks to the GoTo function, the telescope is capable of capturing any astronomical object with its coordinates stored in the microprocessor memory with incredible accuracy. This computer system will provide automatic guidance to more than 42,900 celestial objects. The Levenhuk Skymatic 135 G.T.A Telescope is compatible with OS Windows 7/8.
