Bynostar LE 70-900
The Bynostar LE 70-900 telescope is really the best telescope for older youth. A fully-fledged instrument, it is also very suitable for adults! This 70 mm refractor telescope (also called a refractor) has multi-coated lenses for enhanced contrast transfer and a focal length of 900 mm. Also, this refractor telescope has 36% more light gathering power than a 60 mm entry-level model. As a result, this telescope enables you to distinguish fainter stars than is possible with a conventional telescope. This refractor telescope can easily reveal multiple cloud bands on Jupiter, the rings of Saturn and craters on the moon up to ± 2 km size. The other planets, except Pluto, are also revealed. Needless to say, various deep-sky items such as the brightest Messier objects, are clearly visible.
This Bynostar LE 70-900 telescope (part of the Bynostar telescopes series) is very well-equipped indeed. It has an aluminium charcoal-gray tube, a dew shield, a 5x24 finder telescope, 3 eyepieces, a SR4, H12.5 and H20, all in the international standard size of 1.25 inches (31.75 mm), a zenith prism for convenient observation, 3x Barlow lenses for tripling the magnification used, a motor drive 1 EQ and an equatorial mounting (parallel to the earth axis)!
This mounting allows you, if properly set up, to compensate for the rotation of the earth with a single move. So you do not have to continuously adjust two axes to follow the motion of stars across the sky, but you can do it with just one hand. With the motor drive you can even continue to observe hands-free! Your object is not running out of the picture all the time, but it stays nicely in the middle. This allows you to concentrate better and you can just see more detail than with a stationary telescope!
The resolution is 1.6 arc seconds and the weakest apparent star magnitude 11.3. See the stars!
