Bynostar LE 90-900 telescope
Bynostar LE 90-900 telescope is simply a beautiful refractor telescope (also called refractor). Equipped with a multi-coated lens of 90 mm and a focal length of 900 mm, this telescope collects up to 225% more light than a conventional 60 mm model. The resolution is matchless: 1.3 arc seconds.
With a clear and quiet sky it reveals the Great Red Spot on Jupiter and the Cassini division in the rings of Saturn. Moon Craters of up to 1.6 km are discernible. Contrast transfer is realised by the multi-coated top. Partly because of this the viewer is also very sharp in detecting deep sky objects. The Andromeda system and the Trapezium in the Orion Nebula are readily seen. Also open star clusters, planetary nebulae, and extragalactic systems like M81 and M82 fall within the range of the telescope, like many other Messier objects.
Equipped with a heavier equatorial mount than his little brother of 70mm, the Bynostar LE 90-900 telescope fulfills all the needs of an amateur astronomer. Even the electric drive for the hour axis (motor EQ 2) from Technolyt comes standard with the telescope. To the standard equipment of this Bynostar also belong two top eyepieces: Super Plössls with a focal length of 25 and 10mm for 36x and 90x magnification. Obviously this device accepts 1.25 inch eyepieces. A large 6x30 finder, a zenith prism and an aluminum tripod are also supplied as accessories. Super Plössls with both lower and higher magnifications are available as options. With a limit magnitude of 11.9 this instrument will go just one step further!
