Orion AstroView 120ST EQ Refractor

Refractors have long been touted as great instruments for studying the planets and Moon. But with its shortened focal length and generous aperture, our new Orion AstroView 120ST (for "Short Tube") takes refractor usage to new depths—as in deep sky!

The Orion AstroView 120ST EQ Refractor is a compact, rich-field refractor designed for observation of nebular clouds, star clusters, and even galaxies. It has the same 120mm (4.7") clear aperture as the standard Orion AstroView 120, but the 120ST's multi-coated achromatic objective lens has a focal length of just 600mm (f/5) compared to 1000mm (f/8.3) for the standard model. That translates to a 66% wider field of view for any given eyepiece. With the included 25mm Plossl, the 120ST covers a sprawling 2.1° swath of sky — enough to display the entire Double Cluster, Pleiades Cluster, or North America Nebula! The fast f/5 optical system of the Orion AstroView 120ST EQ Refractor also makes it an excellent telescope for astrophotography.

The Orion AstroView 120ST has a well-baffled optical tube to ensure good contrast. The cast-metal 2" rack-and-pinion focuser accommodates either a 1.25" or 2" diagonal, so you can use optional 2" eyepieces for an even dreamier wide-field effect! The 6x30 finder scope features an aluminum dovetail bracket with easy, two-screw adjustment. The two 1.25" Sirius Plossl eyepieces provide good, sharp views at 24x (25mm focal length) and 60x (10mm focal length). A 1.25" mirror star diagonal is also included.

The optical tube of the Orion AstroView 120ST EQ Refractor measures just 26" long including dew shield, so it earns high marks for portability. It comes with the Orion AstroView equatorial mount, which provides the stability and smoothness of motion you need for enjoyable wanderings through the heavens. A free polar-axis scope gets you polar-aligned quickly and accurately, and manual slow-motion controls let you center objects and track them effortlessly. Add an optional EQ-3M electronic drive for automatic tracking. The aluminum tripod adjusts in height and includes a roomy accessory tray.

The Orion AstroView 120ST EQ Refractor telescope was not designed for high-power examination of planetary or lunar surface detail; for that we recommend the AstroView 120, with its longer focal length. Rather, the 120ST excels for breathtaking, wide-field images of deep-space delectables set against their stellar backdrops. A new refractor with a new purpose — that's the Orion AstroView 120ST EQ!
