Celestron AstroMaster 90 EQ Equatorial Refractor Telescope 21064 Product Info

Celestron AstroMaster 90 EQ Equatorial Refractor Telescope 21064 is a dual-purpose telescope that is great for both terrestrial and celestial viewing. The Astro Master 90 EQ Telescope by Celestron produces bright and clear images of the Moon and planets through the telescope 's Fully Coated Lens. The Refractor Telescope has a 90mm Lens, giving the user a larger lens than the AstroMaster 70mm EQ Telescope. This larger lens will allow more light through when viewing distant objects, such as the moons of Jupiter and the rings of Saturn. Also, these Celestron Telescopes come with two eyepieces of 50X and 100X magnification, which can pull in objects both near and far away. Celestron AstroMaster 90 EQ Telescopes have an Equatorial Mount that allow the user to follow objects in the sky much easier than an Altazimuth (Alt-az) Mount. Equatorial mounts use a set of counterweights that balances the telescope as it moves, making the movement more smooth. This is also very effective in high magnifications, when the smallest nudge of the telescope will greatly affect the viewing area. In addition, Celestron AstroMaster Telescopes are very child friendly with their Refractor design, making them easy to maintain, and able to withstand continuous use. These Telescopes come with a Tripod with 1.25" thick steel legs, providing a rigid and stable platform. These features of the Celestron AstroMaster 90 EQ Telescope 21064 make it a great telescope for beginners and intermediate users.

The Celestron AstroMaster 21064 KIT comes with:

The Celestron AstroMaster 90 EQ Equatorial Telescope Refractor 21064 is also available with an Altazimuth Mount (Model #21063)

Helpful Negative Review A bad telescope in design and workmanship by Legacy Reviewer, October 8, 2011
The telescope's OTA is lightweight and the dew cap is coming removed in hand completely whenever I remove the lens cap. Instead of pressure fitting this dew cap, Celestron must have fixed it firmly to the OTA. The counterweights have a pin stuck at t...
