BYNOSTAR LE 70/900

The better telescope for the older youth, but also for adults a venerable instrument. This 70 mm refractor has multicoated lenses for an even better contrast and a focal length of 900 mm. This refractor also has 36% more light gathering power than the conventional 60 mm models, so you can see fainter stars than with the standard 60 mm scope. With this refractor you can see without any trouble the clouds and belts of Jupiter, the rings of Saturn and craters on the moon of at least 2 km wide. All other planets (except for Pluto) are being revealed. And of course numerous deep-sky objects, like the Messier objects, are visible.

This Bynostar is very complete. An anthracite coloured telescope of aluminium, dew cap / sunshade, a 5x24 finder scope, 3 eyepieces, a SR4, H12,5 and a H20, all in the international standard size of 1,25 inch (31,75 mm), a zenith prism for comfortable observing, 3x Barlow lens which triples the magnification, a motor drive EQ 1 and an equatorial mount (parallel to the earth's axis).

This mount allows you to compensate the rotation of the earth with one movement, provided that you've aligned your mount to the celestial pole. So you don't have to correct the movements of the stars in the sky with two axis, you can do it with one hand. With the help of a motor-drive you can observe hands free. And the object will stay centred. In this way you can concentrate better on your object and you'll see more details.

The resolving power is 1,6 arc second and the faintest visible star 11,3.
