The Orion SkyQuest XT10 Classic 10" Dobsonian reflector makes big-aperture astronomy affordable, portable, and fun. Its huge light grasp and outstanding deep space performance will wow even the experienced observer, much less the newcomer to astronomy.
A review in Astronomy magazine said that the 10" Orion SkyQuest XT10 Dobsonian “offers a pleasing design, great optics . . . I have to say the XT10 [Classic] possesses the best mass-produced Newtonian optics I have seen."
The Orion SkyQuest XT10 Classic’s great light-gathering capacity (over 1300 times that of the human eye) makes it ideal for capturing very faint deep space wonders from a dark sky observing site. Binary stars, open and globular star clusters, faint nebulas and galaxies – all are revealed in exceptional and subtle detail. At the same time, good planetary and lunar images are yours for the looking, although a neutral density or variable polarizing filter is invariably needed to cut down the brightness of these solar system objects.
The Orion SkyQuest XT10 is human powered. You move the scope manually – which is faster, quieter, and much less expensive than a motorized system. With only two major components to assemble (tube and base), and a heaviest single component weight of a little under 31 pounds, the scope takes only a few minutes to set up and is easily managed by any reasonably fit individual. It can be used in your back yard or at a distant dark sky site (the preferred observing location if you want to get the most out of its faint object observing capabilities). Its good optical quality and very reasonable price for such a big telescope make it an excellent buy for the beginning and advanced astronomer alike.
