Celestron AstroMaster 130 EQ Equatorial Reflector Telescope 31045 is a dual-purpose telescope that is great for both terrestrial and celestial viewing. The Celestron Astro Master 130 EQ Telescope produces bright and clear images of the Moon and planets through the telescope's fully coated lens. The Celestron Astro Master 130 EQ Telescope w/ Equatorial Mount has a large 130mm mirror, making it a great medium-sized telescope that will allow the user room to grow in astronomy. This 130mm mirror is the largest mirror in the AstroMaster Series, and will easily provide enough light to see the moons of Jupiter, rings of Saturn, star clusters, and nebulae. These telescopes come with two telescope eyepieces of 50x and 100x magnification, which can pull in objects both near and far away. Celestron AstroMaster 130 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, these Celestron AstroMaster Telescopes have the reflector design, which is favored by astronomers with their more advanced setup and controls, when compared to a Refractor telescope. These telescopes come with a tripod with 1.25" thick steel legs, providing a rigid and stable platform. These features of the Celestron AstroMaster 130 EQ Equatorial Reflector Telescope 31045 make it a great telescope for serious beginners and intermediate users.
