Refractor Telescope 70/700
 
Observing the stars like a professional - very easy with the refractor telescope 
70/700 NG.This refractor telescope with 70mm aperture can show many details in celestial
 objects.The 8845000 is a complete system for the exploration of the wonders of the
 universe,consisting of telescope, mount, tripod and all accessories needed. The mount can
 notonly swing the telescope left / right and up / down, it can also be used in a so-called
 equatorialmode, as scientists do in their observatories (see further under Special
 features).An additional fi nder scope mounted on the telescope is useful for locating
 celestial objects.With the erecting lens during the day many exciting things in the
 environment canalso be seen. With the height-adjustable tripod, the telescope can each be
 brought toan optimal height for large or small observers. The supplied diagonal mirror
 ensures a comfortable viewing.
 
 
APPLICATION
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 fog
impress young and old stargazers.
The included erecting prism to get a true sided and upright image during the day enables
this telescope to be used for the observation of nature, for example.
 
SPECIAL FEATURES
" Mounting with wedge: At fi rst glance, the NG mount for 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.
