  • More Info
    • Sharp 102mm (4.0") lens optics with 700mm focal length excel at resolving star clusters, nebular clouds and detailed views of the Moon and planets
    • Sturdy EQ-13 equatorial mount features a stainless steel tripod and slow-motion controls for convenient manual tracking of celestial objects
    • Two quality 1.25" Plossl eyepieces are included: a 25mm for 28x magnification, and a 10mm for getting in tight at 70x. Barrels are threaded to accept optional Orion filters
    • Highly portable: the optical tube can be removed from the mount quickly via the dovetail mounting system and carried separately
    • Includes Orion's handy MoonMap 260 to aid in identifying and viewing some 260 craters, mountain ranges, "seas" and other fascinating lunar features

    The Orion AstroView 102mm Equatorial Refractor Telescope will delight new and even intermediate-level stargazers with its sharp optics, sturdy equatorial mount, and classical, low-maintenance design.

    With an intermediate focal length of 700mm (f/6.9), the AstroView 102mm EQ has more magnifying power than "short tube" refractors but a wider field of view (1.9 with the included 25mm Plossl) than "long tube", longer focal length telescopes. The 102mm diameter (4.0") fully multi-coated achromatic objective lens excels at revealing mountains and craters on the Moon in vivid relief. It also provides enough light grasp to resolve brighter deep space curiosities like star clusters and nebular clouds. And because the Astroview 102 EQ is a refractor, its optics are precision aligned at the factory and never have to be adjusted by you! That's a nice benefit of a refractor compared to, say, a reflector telescope, which requires periodic collimation by the user.

    At the back end of the AstroView 102 EQ's aluminum optical tube is a 2" aluminum rack and pinion focuser. It includes a step-down adapter to accommodate the included 1.25" 90-degree mirror diagonal and 25mm and 10mm Plossl eyepieces. These quality eyepieces provide magnifications of 28x and 70x respectively, and have barrels threaded for optional Orion 1.25" filters. The 2" focuser allows use of an optional 2" diagonal and 2" eyepieces, if desired, for breathtaking wider-field views. The included EZ Finder II red dot scope makes it easy to aim the AstroView 102 EQ precisely to your target.

    The sturdy EQ-13 equatorial mount boasts smooth tracking capabilities, whether utilized manually with the slow-motion control cables provided or with an optional electronic drive for hands-free tracking. The adjustable-height stainless steel tripod features a twist-on accessory tray so you can keep any additional eyepieces and accessories within arm's reach. What's more, the mount is equipped with a Vixen-style dovetail saddle that allows you to quickly attach or remove the optical tube — which has a compatible dovetail mounting bar — without tools.

    And as a bonus, we're including with this telescope our MoonMap 260 to help you identify and view some 260 craters, mountains, "seas" — even spacecraft landing sites – on the lunar surface. It's a super helpful reference the whole family will enjoy using any night the Moon is up.
