Levenhuk Skyline 120x1000 EQ Reflector Telescope Review

Levenhuk Skyline 120x1000 EQ Reflector Telescope

Levenhuk Skyline 120x1000 EQ Reflector Telescope


Levenhuk Skyline 120x1000 EQ is a Newtonian reflecting telescope. Its mirrors produce no chromatic aberration, which may be especially noticeable during observations of brighter objects with a refracting telescope. The long focal length of this telescope makes it the perfect choice for observations of planets, features of the lunar surface and binary stars. The large, 114-mm primary mirror gathers so much light (2.25 times more than its 76-mm counterpart) that this telescope produces very detailed views of bright deep-sky objects. Additionally – thanks to the capabilities of this telescope – you can even try your hand at astrophotography. The equatorial mount that comes with Levenhuk Skyline 120x1000 EQ makes this telescope even more practical and precise. Overall, this instrument will make a wonderful addition to the equipment of any amateur stargazer. 120mm Newtonian Reflector Telescope. German Equatorial Mount. 25mm and 10mm eyepieces. 5x24 finderscope. 1000mm focal length (f/8.8).

Levenhuk Skyline 130x900 EQ Reflector Telescope Review

Levenhuk Skyline 130x900 EQ Reflector Telescope

Levenhuk Skyline 130x900 EQ Reflector Telescope


Levenhuk Skyline 130x900 EQ is a Newtonian reflector, which is most suitable for the study of deep-sky objects. It is also perfect for observation of planets, even the most remote ones: Jupiter, Saturn, or asteroids and comets. NGC objects, many in high detail, are reachable as well. The telescope provides a clear and sharp image.   Features:   Suitable deep sky objects study: nebulae, galaxies, globular clusters and faint stars Fairly small overall dimensions for the focal length of 900 millimeters (35.4 inches) Contrast and sharp images without distortion Can be used for astrophotography   The equatorial mount, as opposed to an azimuth one, when being hovered compensates for the rotation of the Earth and allows more precise tracking of astronomical objects, keeping them within sight through the eyepiece. This mount is perfect for astronomical observations and indispensable for astrophotography. The aluminum tripod has adjustable height.   Two achromatic eyepieces SUPER 10 and SUPER 25 with a 1.25-inch (31.75-millimeter) diameter are included in the package and serve as powerful image correction tools. The optics used in the eyepiece are glass-coated. Field of view is 50-52 degrees. Large 130mm Newtonian Reflector telescope. German Equatorial Mount. Full Size Tripod. 25mm and 10mm eyepieces. 6x24 finderscope.
