Celestron Astromaster 90EQ telescopes

If you are looking for a telescope that works both on the ground and in the heavens, the AstroMaster series telescopes are the fulfillment of your prayers. All AstroMaster models feature a high-quality, upright image display of both landscape and celestial bodies.

AstroMaster series telescopes provide a clear, clean view of the Moon and planets. You can easily distinguish the moons of Jupiter and the rings of Saturn with all the great devices in the series. For observing brighter deep-sky objects such as galaxies and star nebulae, we recommend the wider aperture and better light-gathering ability of Newton-type mirror telescopes.
