Now everyone with a curiosity for space can explore its wonders to their hearts' content. With an Orion SkyQuest XT4.5 Classic Dobsonian reflector telescope stargazing is easy and fun for the whole family. Its portable size, innovative design, and point-and-view simplicity make it an extremely user-friendly telescope for beginners and intermediate stargazers alike
The Orion SkyQuest XT4.5 Classic Dobsonian's Newtonian reflector tube assembly features a big 4.5" (114mm) diameter light-gathering mirror housed in an enameled steel tube. This spherical primary mirror pulls in 260% more starlight than the lens of a 60mm refractor (the classic beginner telescope). More light means you can see a lot more celestial objects in greater detail. The 4.5" Classic Dobsonian is a great telescope for surveying the Moon's many craters, valleys, and mountains. It's relatively long focal length and f/8 focal ratio provides well-defined views of Jupiter's cloud band "stripes" and nearby Galilean moons, not to mention Saturn and its awe-inspiring rings. This telescope is not limited to only view objects in our solar system. The SkyQuest XT4.5 Classic Dob is a great telescope to use while star-hopping among the Milky Way's diverse star clusters and nebulas.
Packed with great features, the Orion SkyQuest XT4.5 Dobsonian Telescope comes complete with an assortment of useful accessories so you'll be ready for stargazing action as soon as you open the box.
Accurately aim the SkyQuest XT4.5 Dobsonian with the included 6x26 correct-image finder.
Instead of a small 5x finder scope or reflex sight like you get with most beginner scopes, you get a 6x26 correct-image finder scope with the XT4.5 Dobsonian, which makes it easier to accurately aim the telescope at celestial objects of interest. The finder's correct-image view matches naked-eye vision for simple and effective aiming. Sharp crosshairs in the finder makes it easy to center objects in the telescope's field of view.
Explore the cosmos at different magnifications with two included Sirius Plossl eyepieces.
Two fully coated 1.25" Sirius Plossl telescope eyepieces are included with the XT4.5 Dobsonian: a 25mm for wider-field views at 36x power magnification, and a 10mm for getting in close at 91x power. We recommend starting out with the lower-power 25mm eyepiece to see a bigger "window" of night sky, then swap in the 10mm eyepiece for close-up views. Both eyepieces are threaded to accept optional Orion filters which can enhance observations (filters sold separately).
Dial-in celestial details with the smooth adjusting 1.25" rack-and-pinion focuser.
The SkyQuest XT4.5 Classic Dobsonian reflector telescope features a robust, 1.25" rack-and-pinion focuser built to accept any 1.25" Orion eyepiece or accessory. The smooth focus control makes it easy to dial-in fine details when observing objects in the night sky, whether you're looking at a rocky lunar crater or a wispy nebula. The focuser features two knurled thumbscrews to secure inserted 1.25" eyepieces and accessories in-place.
Use the built-in navigation knob to slew the XT4.5 Dob from target to target.
The XT4.5 Dobsonian telescope's enameled steel reflector optical tube boasts a handy "navigation knob" for easy slewing, or re-positioning of the telescope. To aim the XT4.5, or move it from target to target, simply take hold of the navigation knob near the front opening of the reflector tube and gently move the telescope up or down and left or right as desired. Not only does this handy knob make slewing easy, it also helps keep the tube itself nice and cool in temperature for optimal viewing performance.
Orion CorrecTension springs make setup easy and keep the telescope balanced.
Like our other critically acclaimed SkyQuest Classic Dobsonian reflector telescopes, the XT4.5 sports our exclusive Orion CorrecTension Friction Optimization system for superior optical tube balance and motion control. The CorrecTension springs also keep the tube securely fastened to the Dobsonian base, so the whole telescope can be carried as a single unit by the handle installed on the tube. There's no setting up or dismantling needed each time the telescope is used. That's a big plus!
Enhance your explorations of the Moon with extra included accessories.
This special Moon Kit includes the complete Orion SkyQuest XT4.5 Classic Dobsonian Telescope, a useful 1.25" Orion 13% Transmission Moon Filter, and a detailed Orion MoonMap 260. The versatile Moon Filter can be attached to any 1.25" eyepiece, and it's 13% neutral-density filtration helps reduce the Moon's bright glare which can significantly improve clarity and contrast of lunar features such as craters, mountains and valleys. The included Orion MoonMap 260 identifies over 260 of the most popular lunar surface features including craters, mountain ranges, valleys, rilles, "seas" and more. Each feature is cross-referenced in the MoonMap's tables with its official name, size and a brief description.
The Orion SkyQuest XT4.5 Classic Dobsonian telescope has been designed with ease-of-use in mind. It's a true "Dobsonian" telescope, having all the great features and value that make the Dobsonian reflector design so popular. Intuitive up-down, left-right altazimuth maneuverability makes it a cinch for everyone in the family to use the XT4.5 reflector telescope. As with other Orion Classic Dobsonian telescopes, you don't have to worry about lock knobs or other balancing adjustments. The SkyQuest XT4.5's stable Dobsonian base provides sturdy support of the reflector optical tube, and it features non-stick PTFE/Nylon bearing pads so the scope glides smoothly with just a gentle nudge of the navigation knob on the front of the telescope. The Dobsonian base provides far greater stability than the tripods included with most beginner scopes, so your views will always be steady and free of frustrating vibrations and shakes.
