As any telescope aficionado will tell you, the virtue of a refractor lies in its pristine image quality. The only challenge to owning a refractor has always been the price: refractors cost more per inch of aperture than any other telescope design. That's still true, but steady advances in precision lens manufacturing technology are bringing those prices down.

Way down, in the case of our remarkable Orion AstroView 90mm Equatorial Refractor Telescope. This impressive 90mm refractor telescope is priced to please, without compromising the quality of the optics, equatorial mount or standard accessories, we might add. This is a soundly constructed, great performing telescope that any new backyard astronomer or experienced stargazer will appreciate from the first night out.

The Orion AstroView 90mm EQ Refractor is a planetary power-performer with its 90mm aperture and 910mm focal length. Views of the planets and Moon through the f/10 AstroView 90 telescope are nothing short of spectacular. When aimed at our nearest neighbor in space, the Moon, the AstroView 90 yields tack-sharp views of the rocky lunar surface with craters and mountainous regions visible in crisp, high-contrast detail. You'll find yourself transfixed by the rugged relief of the Moon's surface as shadows along the terminator enchant your eyes. On a reasonably clear evening, Jupiter's cloud banding becomes starkly visible, as do all four of its major Galilean moons. Depending on the time of year, the Orion AstroView 90mm EQ Refractor can also provide the whole family with jaw-dropping views of Saturn and its stunning rings, not to mention glimpses of Saturn's largest moon Titan.  

With 90mm of aperture, the AstroView 90mm Equatorial Refractor Telescope can also provide great views of many deep-sky phenomena. With the 25mm Plossl eyepiece installed in the telescope to provide 36x power magnification, our namesake deep-sky object, the Orion Nebula, exhibits the four Trapezium stars as perfect blue pinpoints surrounded by a pretty patch of greenish gas. If you pop in the included 10mm eyepiece to bump up the power to 91x magnification - wow! - the nebula will appear sprout cloudy wings, which span nearly the entire eyepiece field of view!

Begin your night sky explorations with the included 25mm Sirius Plossl Eyepiece.

The included 1.25" Orion 25mm Sirius Plossl eyepiece provides a 36-power view when used with the AstroView 90mm refractor telescope. Using this eyepiece's moderate magnification is a great way to begin exploring interesting objects in the sparkling night sky. Offering a wide 52° apparent field of view, the 25mm Sirius Plossl eyepiece yields extremely sharp images of impressively high contrast. You'll be amazed at the crisp, clear views of sights like the cratered surface of the Moon and much more!

Take a closer look with the included 10mm Sirius Plossl Eyepiece.

When you're ready to study objects with more magnification, use the included 10mm Sirius Plossl eyepiece. When inserted into the AstroView 90 mm refractor telescope, the 10mm Plossl provides a powerful, 91x view with a 52° apparent field of view, so you can inspect interesting objects more closely. We recommend starting out with the lower-power 25mm Plossl, then switching to the 10mm ocular to boost the power of your telescope's view.

Use the included 90° star diagonal to view the night sky comfortably.

A diagonal "bends" the light path of a telescope so you can enjoy the view without having to contort yourself into awkward positions to peer into the eyepiece. The 90° star diagonal that comes with the AstroView 90mm refractor places the eyepiece you're using in a comfortable position for nighttime stargazing of the skies above.

Aim the telescope accurately with the included 6x30 finder scope.

Following a simple alignment procedure, you can use 6x30 finder scope to accurately aim the AstroView 90mm refractor at objects in the sky like the Moon, bright planets, nebulas and star clusters. Once aligned with the telescope, just peer through the finder scope and move the telescope until the cross hairs are centered on the object you want to see. Look in the telescope, and it'll be right there!

The included EQ-2 equatorial mount provides stable support and slow-motion control.

The AstroView 90mm refractor is supported by the substantial Orion EQ-2 equatorial mount, which allows for easy manual tracking of celestial objects as they appear to migrate across the night sky. An occasional tweak of the equatorial mount's R.A. (Right Ascension) slow-motion cable will keep any object centered in the telescope eyepiece.

Use the Moon Filter that comes with the telescope kit for great lunar views.

Improve your telescopic explorations of the Moon by using the included Orion 13% Transmission Moon Filter. The threaded filter is easy to install on the included 25mm and 10mm eyepieces, and its neutral-density filtration will help enhance contrast of craters, mountains, and other interesting lunar features. The 13% transmission filter also helps reduce the bright glare of the Moon to make observations more comfortable.

Enhance interesting features with the included Four Color Planetary Filter Set.

Color filters help reveal subtle surface features and markings on planets such as Jupiter, Saturn and Mars as well as the Moon by selectively increasing the contrast between markings of different hues. The included Filter Set comes with our most popular color planetary telescope eyepiece filters: #15 Deep Yellow, #25 Red, #58 Green, and #80A Medium Blue.

The Orion MoonMap 260 makes it easy to learn about the Moon's landscape.

With locations and names of over 260 features on the Moon such as craters, mountains, valleys, "seas" spacecraft landing sites, and more, the Orion MoonMap 260 included with this telescope kit is a great tool for all amateur astronomers. The whole family will enjoy using the MoonMap 260 to properly identify all those craters and other lunar features the Moon Filter and Color Filters help accentuate.

Find your way around starry skies with the included Star Target planisphere

Whether you're skywatching with just your eyes or through a telescope, a planisphere star chart is an essential tool you'll use time and time again. The included Orion Star Target is a vital reference tool for learning the constellations, identifying stars, and locating popular bright celestial objects such as galaxies, star clusters, and cloudy nebulas. Simply dial in the date and time, and StarTarget shows you the sky overhead.

The AstroView 90mm refractor's adjustable tripod lets you set the telescope to a comfortable height for a long night of solo stargazing, or you can change the height throughout the evening for a night of family fun with the stars. There's even a handy accessory tray that fits onto the tripod for convenient storage of gear while you're out in the field.  

 

The Orion AstroView 90mm Equatorial Refractor Telescope will provide you and your family with many evenings of heavenly browsing at an unbelievably low price. The assembled telescope weighs just 23.7 lbs. total, so it's easy to take outside for impromptu observing sessions.
