Orion Sirius 120ED EQ-G Refractor with Dual-Axis Drive


  • Superb 120mm ED optics and fine craftsmanship compare to large refractors costing thousands more
  • Premium system excels for observing or photography of deep-sky and planetary targets
  • Sirius EQ-G Dual-Axis Equatorial Mount provides stability and control
  • Includes dual-axis electronic hand controller. GoTo Hand Controller can be purchased separately
  • Comes with 2" mirror diagonal that accepts 1.25" eyepieces, 26mm Pl?ssl eyepiece, and 8x40 finder

For the most demanding amateur astronomer, this premium telescope combines superb optical performance, rock sold stability, and precise automatic object location at a remarkably affordable price. Comparable to big refractors costing thousands more, the 120ED EQ-G is worth considering if you are really serious about observing or photography.

The optical system is simply stunning. Delivering 43% more light grasp than 100mm optics, the 120ED expands your reach into deep space while providing more detail and higher magnification for planetary work. FPL-53 extra-low dispersion (ED) glass in one of the two lens elements and 900mm focal length (f/7.5) mean stars, planets, and the lunar limb will show their true colors without chromatic aberration. All air-to-glass surfaces are fully multicoated.

The Sirius EG mount and dual-axis controller combine to give you stability for high-power photography and viewing. You can upgrade to a GoTo controller at any time.

This deluxe system includes a CCD autoguider port for photography, periodic error correction (PEC), latitude and azimuth adjustments for polar alignment, and an illuminated polar axis scope. The tripod features 1.75" stainless steel legs and a cast metal spreader plate.

Requires a 12-volt DC power source, such as Orion Dynamo Pro (#2307), or an AC-to-DC adapter (#7728) for use with household 110-volt power. One-year limited warranty.
