The\u00a090\/900 refractor<\/b>\u00a0telescope\u00a0<\/b>is a classic and can be used for either astronomy or nature observations (e.g. of wild animals). The long focal length (900 mm) makes the\u00a0telescope\u00a0<\/b>a specialist for observing the moon, planets and bright objects outside our solar system. Saturn’s majestic rings and giant storms on Jupiter can be seen, as well as bright emission nebulae, galaxies and star clusters if you observe on a dark, moonless night away from city lights. The sturdy\u00a0equatorial mount\u00a0<\/b>can be pointed to the North Star, Polaris, and tracking objects by hand is child’s play.<\/p>\n
