Product description

National Geographic's AC 90/900 EQ-3

The 90/900 refractor telescope gathers a lot of light with it`s 90mm aperture. The long focal length (900mm) 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 bright emission nebulae, galaxies and star clusters if you observe on a dark, moonless night away from city lights. The sturdy equatorial mount can be pointed to the North Star, Polaris, and tracking objects by hand is child's play.

The EQ-3: This equatorial mount provides the opportunity to precisely align scopes with Polaris. The correct pole height or geographical latitude can be set for each observation site. Thanks to fine movements along the right ascension and declination axes, objects can be precisely located, followed and kept within the visual field. A counterweight precisely balances the telescope.
The EQ-3 mount provides a solid base for most smaller and medium-sized scopes and is very well suited to spacewalks through the night sky. The tripod is extendible and a shelf provides space for eyepieces and other accessories.

It not only matters which telescope you buy but also where you buy it. Our additional services:

  • We are a leading telescope dealer and know the devices we sell. Our customer service team will gladly help you after your purchase if you have problems with assembly or operation.
  • We provide a copy of the 80-page Telescope ABC beginners handbook with every telescope.
