Orion SkyQuest XT10g Computerized GoTo Dobsonian Telescope

Orion SkyQuest XT10g Computerized GoTo Dobsonian Telescope Reviews


Other Picture


Orion SkyQuest XT10g Computerized GoTo Dobsonian Telescope Feature

  • Fully motorized GoTo Dobsonian reflector telescope locates, centers, and automatically tracks any of 42,000 celestial objects with pushbutton ease!
  • Big 10-inch aperture reflector optics gathers plenty of light for pleasing views of galaxies, nebulas, and star clusters as well as bright close-up study of the planets and Moon
  • Computerized GoTo motors, encoders, and gears come pre-installed on the Dobsonian base for easy assembly
  • Requires 12V power supply (sold seperately) for motorized operation
  • Includes 2-inch dual-speed (11:1) Crayford focuser, 28mm 2-inch DeepView eyepiece, 12.5mm 1.25-inch illuminated crosshair Plossl eyepiece, EZ Finder II reflex sight, eyepiece rack, collimation cap, and Starry Night software
Orion Dobsonians have always been known for superb optical and mechanical quality, wonderful ease of use, and remarkably affordable prices. One other thing they - and almost all other Dobs on the market - have had in common: you pushed the telescope to your observing target by hand. Until now. Orion is pleased to herald another giant leap in Dobsonian evolution with the introduction of the SkyQuest XTg series of fully motor driven GoTo Dobsonians. Now, pointing a Dob to even the most elusive of NGC curiosities is as easy as pushing a button or two on the XTg Dobsonians' illuminated hand controller. High-torque servo motors guided by two pairs of high-resolution encoders then slew the telescope right to your object of interest - any of over 42,000 objects in the GoTo controller's database. No more nudging the telescope tube continuously to keep the object from drifting out of the field of view, either. The XTg automatically tracks the object's motion, keeping it centered in the eyepiece while you savor the view. What's more, the closed-loop electronics of the XTg let you move the telescope manually - or endure the accidental bump - without losing orientation for accurate, automated GoTo pointing!

  • A complete portable big-aperture telescope set - includes our innovative XX12i Truss Tube Dobsonian, view optimizing Light Shroud, and custom Case Set to hold and transport the optical tube components safely
  • Traditional 8-truss reflector optical tube design offers superior optical tube rigidity compared to other designs in this category
  • IntelliScope computerized object locating technology pinpoints any of 14,000 objects in seconds
  • Included custom-designed light shroud for the SkyQuest XX12i telescope to block stray light to improve image contrast
  • Included three case set designed to protect the optical tube sections of the SkyQuest XX12i Truss Tube Dobsonian reflector during transport
If the idea of a big-aperture telescope appeals to you, but the portability issue has kept you on the fence, you can hop off it now. We've got the perfect solution - the SkyQuest XX12i IntelliScope Truss Tube Dob. It's a deep-sky observer's dream scope, offering jumbo 12" Pyrex optics (f/4.9); a stylish, reduced-weight base outfitted with IntelliScope object location technology; and a sturdy truss tube design that disassembles in about a minute into compact, easily portable components. Finally, a deluxe, large-aperture Dobsonian that fits comfortably in a compact car for transport to your favorite observing site! The eight trusses (four captive pairs) provide more-rigid support than other designs in this category. We've also outfitted the XX12i base with nothing but the best materials: EbonyStar laminate and Virgin Teflon azimuth bearing surfaces provide silky smooth azimuth motion. Equipped with dual-speed (11:1) 2" Crayford focuser, large 8" altitude bearings, full set of great accessories, a computerized database of 14,000 celestial objects -- and a price just north of a grand! -- the XX12i is one killer telescope deal.

Skywatcher 10" Dobsonian 1200mm Focal Length (f/5.0) with 2" Crayford Style Focuser, 1.25" adaptor, 10mm & 25mm Plossl Eyepieces, 8x50 VF, & Rocker Mount Feature

  • The Sky-Watcher 10" DOB utilizes quality components throughout
  • The polishing process for primary and diagonal mirror yields smooth mirror surfaces ensuring good contrast and properly corrected optics show minimum alterations to the optical wave-front
  • The standard-equipment backlash-free 2" Crayford Focuser insures ultra smooth focusing adjustments
  • An 8x50mm Right Angle optical viewfinder provides both magnification and light gathering to help narrow your search for those elusive fuzzies when star-hopping
  • To ensure mechanical ease-of-use, SW uses a high-performance Teflon bearing system in both axes combined with tension adjustment in altitude to facilitate setting the appropriate amount of friction
The Skywatcher 10" DOB is an very satisfying telescope to own, an instrument that will provide a lifetime of continuing exploration of the heavens. This telescope provides all the capability and value you are seeking in a large aperture telescope. Skywatcher's revolutionary truss-support concept allows the optical tube's front and back cells to collapse together, aligning on the truss support rods which can then be locked down for easy and secure telescope transport. This one piece, low-hassle OTA design is mechanically simple and results in a large aperture telescope that can be reasonably handled and transported by one individual. This innovation gives Skywatcher users tremendous functional ease-of-transportability. With this telescope you have tremendous light gathering power. Prominent deep-space objects seen well in an 8" SW DOB, such as diffuse emission nebulae in the summer sky like the Lagoon (M8), Trifid (M20) and Swan (M17); the stunning globular star clusters M13 and M92 in Constellation Hercules; the awesome winter sky's Great Orion Nebula (M42) in Constellation Orion and the enormous local galaxy group companion the Andromeda Galaxy (M31) in Constellation Andromeda, to name a very few, will appear more spectacular, brilliant and wider in extension in a SW 10" DOB. Many challenging objects for an 8" aperture now come into their own with the SW 10" DOB: the planetary nebula the Crab (M1), a supernova remnant, requires a 10" aperture t
