  • This Orion SkyQuest XX14G Dobsonian Telescope is an enormous yet conveniently portable telescope equipped with fully motorized GoTo object location and automatic tracking of over 42,000 celestial objects.
  • Colossal 14" aperture reflector optics collect tons of light for wonderfully detailed views of deep space objects such as galaxies, star clusters, and cloudy nebulas, in addition to bright and detailed views of closer cosmic quarry including the Moon and planets.
  • This Orion SkyQuest XX14G Dobsonian Telescope features a collapsible GoTo base and rigid 8-pole truss reflector optical tube both break down into easily manageable components for transport in virtually any car.
  • Closed-loop electronics forgive accidental bumps, nudges, and even manual repositioning without losing alignment of the GoTo system.
  • Heavy-duty clutches allow independent adjustment of motion to desired level of resistance in both axes.
  • Innovative convex-back 356mm diameter parabolic primary mirror and newly engineered mirror cell weigh 10 lbs. less than our standard 14" reflector mirror and cell.


Orion SkyQuest XX14G Go-To Truss Tube Dobsonian Telescope

This pleasantly portable, yet large-aperture Orion Dobsonian is equipped with GoTo motorization and closed-loop tracking, making it an ideal telescope for use in the backyard or at your favorite dark sky site. Not only does the Oron SkyQuest XX14g GoTo Truss Tube Dobsonian feature exceptionally large 14" (356mm) diameter optics, but its Orion-designed collapsible GoTo Dobsonian base and truss tube make the Orion XX14g conveniently portable, since you can break the entire telescope down into bite-size component pieces.

Imagine, a 14" diameter Dobsonian reflector with motorized GoTo object location and tracking, capable of being packed into a small car. The optical tube and base both separate into smaller components - without tools. Once broken down, everything fits easily into even a compact car, for the trip to your favorite dark-sky site. The rigid 8-pole truss tube of the Orion XX14g virtually eliminates flexure observed in 6- and 3-pole collapsible tube designs. Stability of the assembled Orion XX14g Dobsonian base is enhanced by its 1" thick composite wood base panels, which are laminated with water-resistant black melamine. GoTo and tracking motors are pre-installed on the base panels, making assembly nice and easy. Once the tube and base are assembled, the optical tube attaches to the base with a dovetail trunnion and locks securely in place with a single captive hand knob. Since all base and truss tube hardware is captive, you don't have to worry about leaving a screw behind after a long night of viewing in the field.

The Orion XX14g GoTo system automatically slews the telescope to any of the over 42,000 celestial objects you choose from the hand controller's intuitive menus, once a simple alignment process is completed. Altitude and azimuth motors automatically track the motion of the target object so it stays put in the eyepiece field of view for extended visual study. Forgiving of accidental bumps, the Orion XX14g's GoTo system features closed-loop electronics allowing manual repositioning or slewing of the telescope tube without losing alignment. In fact, depending on your preference you can choose to operate the telescope in either GoTo or auto tracking modes. Redesigned heavy-duty clutches allow motion in both axes to be adjusted independently to desired level of resistance.

The 14" parabolic primary mirror doesn't just gobble up photons; it wolfs them down eagerly for your visual inspection. The Orion XX14g features an innovative convex-back 356mm diameter primary mirror and a newly engineered mirror cell, which weighs 10 lbs. less than standard 14" mirror and cell combinations, yielding faster ambient temperature equilibration times so you get optimal visual results more quickly. The mirror cell accepts six specially designed threaded counterweights (included) to optimize balance.

The dual-speed abilities of the 2" Crayford focuser with its 11:1 fine-focus ratio allows you to dial in precise details of any celestial denizen. Both 2" and 1.25" telescope eyepieces can be used, thanks to the included 1.25" step-down adapter.

The Orion XX14g includes both a 2" DeepView 35mm eyepiece for wide views and a 1.25" 12.5mm Plossl eyepiece with an illuminated reticle to help align the GoTo system precisely. Other stellar accessories include an EZ Finder II reflex sight, removable eyepiece rack, GoTo hand controller holder bracket, collimation cap, 12V DC power cable, and RS-232 cable for future firmware updates. A 12V power supply or AC-to-DC adapter (sold separately) is required for motorized operation.

In keeping with Orion's tradition of offering top-notch quality optics at affordable prices the Orion XX14g GoTo Truss Tube Dob is priced to please. Includes a FREE Starry Night Special Edition software CD-ROM and SkyTheater DVD - a $69.90 value! As with all Orion telescopes, our Customer Service and Technical Support teams are available to help with any questions you may have on our exciting new 14" GoTo Truss Tube Dobsonian.

Dark skies await you, and with the Orion XX14g GoTo Truss Tube Dobsonian Telescope, they're well within reach.

When using a truss tube Dobsonian telescope for solar observing, always use a Light Shroud and a properly sized solar filter. When you install the Light Shroud make certain there are no gaps between the Shroud and the telescope where direct sunlight can reach the mirror.

When a truss tube telescope (equipped with a solar filter but no shroud) is pointing near (not at) the Sun, direct sunlight can hit the mirror and focus on the solar fi lter or other portions of the telescope. Th is can lead to eye injury or damage to the telescope. Using a Light Shroud protects your telescope from peripheral sunlight.

Before using any telescope for solar observing, make sure to install dustcaps or other protective covers on all optical components such as fi nder scopes to keep sunlight from passing through them. Glancing through an uncovered optical system even for an instant can cause permanent eye damage.

Always install protective caps on all optical instruments when left outside in direct sunlight during daylight hours.
