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 quality. This is a soundly constructed 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!
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!
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.
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.
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 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. You can also use an optional electronic motor drive for more automated, hands-free tracking of any centered object (drives sold separately).
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.
