Orion® SkyQuest™ XT4.5 Classic Dobsonian Reflector #09804

SkyQuest XT4.5 Dobsonian Reflector

  • ".... a new standard for the beginner's telescope" -- Sky & Telescope (4/01)
  • 114mm aperture and 910mm focal length for views of lunar craters, planets, nebulas, and galaxies
  • Sturdy Dobsonian mount and handy grip knob allow for effortless maneuvering
  • Includes two eyepieces, finder scope, focuser, collimation cap, and FREE Starry Night astronomy soft
  • One-year limited warranty

Now young people with a curiosity for space can explore its mind-boggling wonders to their hearts' content. With the SkyQuest XT4.5, stargazing is easy and fun. Its compact size, innovative design, and point-and-view simplicity make it the user-friendliest telescope for kids to come along in years. Kids ages 8 to 88, that is, because adults will appreciate its portability and excellent optical performace!

Show Me the Cosmos!
The XT4.5's Newtonian reflector tube assembly features a big 4.5"(114mm) light-gathering mirror housed in an enameled steel tube. This mirror pulls in 260% more starlight than the lens of a 60mm refractor (the classic beginner telescope), bringing hundreds more objects boldly into view! Think of it: in a given evening you could survey the Moon's myriad craters, then study Jupiter's cloud bands, then star-hop among the Milky Way's diverse star clusters and nebulas. The XT4.5 is one very revealing telescope!

Designed for Ease of Use
It's also a true "Dobsonian" telescope, having all the great features that make Dobs so popular. Such as intuitive up-down, left-right maneuverability (without lock knobs or other adjustments to mess with) and sturdy support of the optics. The XT4.5's base features Teflon/Nylon bearing pads, so the scope glides smoothly with just a gentle nudge of the tube. The base provides far greater stability than the tripods included with most beginner scopes, so the views are always steady.

Like our other, critically acclaimed SkyQuest Dobsonians, the XT4.5 sports our exclusive CorrecTension Friction Optimization for superior tube balance and motion control. The CorrecTension springs also keep the tube fastened to the base, so the whole scope can be carried as a single unit by the handle installed on the tube. There's literally no setting up or dismantling needed each time the scope is used. That's a big plus, especially for kids.

Not Your Average Accessories!
The SkyQuest XT4.5 comes complete with great accessories. Instead of a small 5x nonachromatic finder scope like you get with most beginner scopes, you get a 6x26 achromatic correct-image finder scope and a "navigation knob" for easy slewing of the telescope. You also get two fully coated 1.25" Sirius Plossl eyepieces: a 25mm for low-power views at 36x, and a 10mm for getting in close at 91x.

Don't kill a budding interest in astronomy with a flimsy department store scope. The SkyQuest XT4.5 is a real telescope, not a toy. It's a quality astronomical instrument capable of delivering high-resolution images of astronomical objects. Which is why Mom, Dad, and the rest of the gang will enjoy using it, too. Hey, the line forms at the eyepiece!
