National Geographic 90/900 Refractor Telescope EQ3 (9070000)
The 90/900 refractor telescope is a classic achromatic refractor and can be used for either astronomy or nature observations (e.g. of wild animals). The long focal length (900 mm) makes the telescope 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 the brighter emission nebulae, galaxies and star clusters if you observe on a dark, moonless night away from city lights. The sturdy equatorial mount can be aligned to the Pole Star, Polaris, and makes tracking objects by hand child's play.
Three eyepieces, a 20mm, 12.5mm and 4mm, giving 45x, 72x and 225x magnification respectively, are included and also a 3x Barlow lens and Moon filter as standard. A red LED reflex finder, once aligned to the telescope's main optical axis, will help you find your way to a huge array of potential targets for observation in the night time sky.
The EQ3 mount is provided with slow motion flexible cables to help you follow objects accurately and compensate for the effects of the Earth's rotation. The mount can also be upgraded to a simple RA motor tracking kit with additional purchase.
