How could you improve upon the refractor of your dreams? Would adding a computerized guidance system do the trick? That's what the GoTo system brings to this venerable refractor. Now, pushing a button or two on the convenient hand controller activates two stepper motors to power the "big gun" to any one of 13,400+ celestial gems at a quick 3.4° per second. The GoTo system can even take you on a guided tour of the celestial highlights for any month of the year. A simple alignment is all it takes to get started. What a great addition to a great telesfcope!

The GoTo system provides computerized electronic control that can pinpoint the location of any celestial target in the hand controller's 13,436-object databank. Backlash compensation and programmable periodic error correction (PEC) provide the responsiveness for guiding and the tracking accuracy needed for astrophotography. The drive base is equipped with a charge couupled device (CCD) autoguider port. The hand controller has a two-line, backlit LCD screen and a red-illuminated keypad. Navigating the menu buttons is very intuitive and takes little time to master. The database includes the complete Messier, NGC, and IC catalogs; eight planets; 100 named stars; and 25 user-defined objects.

With all that convenience you'll have more time to enjoy the sights revealed by an outstanding optical system. With 120mm of clear aperture and 1000mm focal length, the Orion SkyView Pro 120 GoTo Achromatic Refractor can split 2-arcscond double stars and reveal subtle lunar and planetary details. With less chromatic aberration than short-focal-length achromatic refractor telescopes, the SVP 120 provides crisp, pleasing star astrophotography with a minimum of color fringing. Attach an Orion Solar System Color Imaging Camera to capture spectacularly detailed shots of Jupiter, Saturn, Mars, and lunar landscapes galore!

This telescope features a fully multi-coated 120mm (4.7") achromatic objective lens in an adjustable cell. The 2" aluminum focuser (with 1.25" adapter) allows use of optional 2" eyepieces. The optical tube rides on the sturdy SkyView Pro equatorial mount with stainless steel tripod.

The SkyView Pro 120mm GoTo Achromatic Refractor will take you to more amazing places than you ever dreamed possible! The GoTo system requires an external 12-volt power source (sold separately).

For owners of the SkyView Pro EQ GoTo Mount whose version of the GoTo hand controller is 3.0 or greater, the GoTo hand controller's firmware can be updated over the internet.
