Description
The Orion 120mm f/5.0 Compact, Large-Aperture Refractor is perfect for deep-sky pursuits. Its 120mm (4.7"), multi-coated achromatic lens assembly and modest 600mm focal length combine to provide breathtaking wide-field views. With an optional 25mm Plossl eyepiece, this telescope serves up a sprawling 2.1-deg swath of sky! The fast f/5.0 optical system also makes it an excellent telescope for astrophotography.

The 26"-long optical tube is well baffled to ensure good contrast. The cast-metal 2" rack-and-pinion focuser accommodates either a 1.25" or 2" diagonal, so you can use 1.25" or 2" eyepieces. Tube color is gunmetal gray metallic. A mounting base molded into the focuser casting to accept an optional Orion finder scope or EZ Finder II.
