Observing the stars like a professional - very easy with the BRESSER JUNIOR refractor telescope 70/700 EL. It is a complete system for the exploration of the wonders of the universe, consisting of telescopemounttripod and all accessories needed. With an aperture of 70 mm it reveils already many details of celestial objects. The mount can not only swing the telescope left / right and up / down, it can also be used in a so-called equatorial mode, as scientists do in their observatories (see further under Special features). An additional finder scope mounted on the telescope is useful for locating celestial objects. With the erecting lens many exciting things in the environment can also be seen during daytime. With the height-adjustable tripod, the telescope can each be brought to an optimal height for large or small observers. The supplied diagonal mirror ensures a comfortable viewing.

At night the moon and planets may like Saturn and Jupiter can be explored. But thanks to the 70 mm wide aperture of the telescope also many celestial objects outside our solar system are within the reach of this telescope. Star clusters many light years away and nebula impress young and old stargazers.

SPECIAL FEATURES

Mounting with wedge: At first glance, the NG mount of the refractor telescope 70/700 NG is a very ordinary azimuth mount: an axis for left / right and one for up / down, as we know it from normal camera tripods. This mode makes sense especially with observations during the day. With the built-in wedge it can be tilted, so the whole mount can be converted to an equatorial mount for astronomy with a single operation. For use of the equatorial mount an axis is aligned with the North Star. When tracking a celestial object only a single axis needs to be moved, which clearly is a relief compared to tracking an object on the night sky with mounts that only have left / right and up / down axis.
