The Bresser National Geographic 90/900 EQ3 classic refractor is equally good for astronomy and terrestrial observations. A long focal length, an achromatic lens, and maximum magnification of 675x make this telescope one of the best to show you the Moon in detail, Saturn's rings, giant storms on Jupiter, as well as bright emission nebulae, galaxies and star clusters if you observe on a dark, moonless night away from city lights. An equatorial mount is a bit complicated as compared to an azimuthal one, but is much more efficient and is suitable for astrophotography. The telescope comes with three eyepieces, a Barlow lens, and a lunar filter.
