    Refractor telescopes have long been touted as great optical instruments for studying the planets and Moon. But with its short focal length and generous 120mm aperture, our popular Orion AstroView 120ST (ST for "Short Tube") Equatorial Refractor Telescope takes refractor usage to new depths - as in deep sky!

    This compact, rich-field refractor telescope is designed for wide-field observation of nebular clouds, star clusters, and even distant galaxies. The Orion AstroView 120ST Equatorial Refractor Telescope features multi-coated optics and a well-baffled optical tube to ensure good contrast in your views. The refractor telescope optical tube measures just 26" long including the dew shield, so it earns high marks for portability. Not limited to visual use, the fast f/5 optical system makes the AstroView 120ST an excellent refractor telescope to use for wide-field astrophotography in addition to observational astronomy.  

    Large, 120mm objective lens gathers a lot of light for bright wide-field views.

    The Orion AstroView 120ST EQ Refractor has a big 120mm (4.7") clear aperture for great light gathering and big, bright views. The 120ST refractor telescope's achromatic objective lens has a short focal length of just 600mm (f/5) for exceptional rich-field performance. With the included 25mm Plossl, the AstroView 120ST refractor covers a sprawling 2.1° swath of sky - enough to display the entire Double Cluster of Perseus, Pleiades Cluster, or North America Nebula!

    The included 6x30 finder scope will help you aim the telescope accurately.

    The AstroView 120ST comes with a 6x30 finder scope which lets you accurately aim the refractor anywhere in the sky. The finder features a lightweight, yet sturdy aluminum dovetail bracket with easy two-screw adjustment. Once a simple alignment process is completed, 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 there it is!

    Explore the night sky at two different magnifications with the included eyepieces.

    Two included 1.25" Sirius Plossl telescope eyepieces provide good, sharp views at 24x (with the 25mm focal length eyepiece) and 60x (with the 10mm focal length eyepiece). Each Sirius Plossl boast a wide, 52° apparent field-of-view. We recommend starting out with the 25mm eyepiece for a wider view, then once you've centered an interesting object, take a closer look by swapping out the 25mm ocular for the more powerful 10mm eyepiece to explore in detail.

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

    A 90° 1.25" mirror star diagonal provides a comfortable angle at night and yields bright views. 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 cast-metal 2" rack-and-pinion focuser with included step-down 2"-to-1.25" adapter accommodates either a 1.25" or 2" diagonal, so you can use optional 2" gear for an even dreamier wide-field effect! (2" accessories sold separately.)

    The included AstroView EQ mount provides slow-motion control and solid support.

    The AstroView equatorial (EQ) mount provides the stability and smoothness of motion you need for enjoyable wanderings through the heavens. An included polar-axis scope will allow you to achieve polar-alignment quickly and accurately, and manual slow-motion controls let you center objects and track them with minimal effort. To upgrade to motorized tracking, you can add an optional Orion EQ-3M electronic drive for automatic tracking of celestial objects (Orion EQ-3M drive sold separately).

    Weighs 36.5 lbs. total (optical tube 8 lbs., 9 oz.; mount 28 lbs.).
