Celestron Astromaster 90EQ - 90/1000 mm refractor telescope on CG-3 mount
This refractor guarantees fun and ease in observational astronomy, as it is solidly made and simple to use.

The 90 mm refractor collects 65% more light than the 70 mm model, so it´s not only impressive on the moon and planets, but many deep-sky objects can already be seen. Since a refractor, unlike a Newtonian reflector telescope, does not require a secondary mirror in the telescope, it collects just as much light as a slightly larger Newtonian telescope.

The equatorial mount is specifically designed for sky observing: If you align it with Polaris, you subsequently only need to track the telescope in one axis when observing planets at high magnification, for example. This allows you to quickly find your object again, even after a short break. While this makes observing more comfortable, setup is a bit more time consuming because you have to align the mount and balance the telescope with the included counterweights. You do not need any tools for the setup.

Sky performance
The 90 mm aperture lens already shows many thousands of nebulae, galaxies and star clusters. Fine details can also be observed on the moon and planets. The Cassini Division in Saturn´s rings or the "Great Red Spot" of Jupiter are already within the range of the instrument.

Photography of these objects is also possible. Moon and planets can already be photographed well through the telescope. One of the two tube rings even offers you a mount for your camera. So you can use the camera parallel to the telescope and take pictures of nebulae, galaxies or even extended sky fields.

The AstroMaster Telescopes
If you´re looking for a versatile telescope for both sky and Earth observation, look no further than the AstroMaster series. The Amici prism included with the refracting telescopes provides upright, laterally correct images with any eyepiece.

An AstroMaster not only provides breathtaking views of the moon, Saturn with its rings, Jupiter with its bands and moons, nebulae and star clusters. You can also observe solar activity with an optional solar filter. If you are less interested in the solar system and more in the brighter deep sky objects like the galaxies and nebulae, we recommend one of the Newtonian reflectors with larger light gathering aperture.
