Item #  10140

The StarBlast 114mm AutoTracker Reflector makes it easy for the whole family to enjoy night after night of stargazing fun with its combination of great telescope optics and an easy-to-use motorized tracking mount. The 114mm (4.5") aperture reflector telescope tube gathers a substantial amount of light, but remains nicely compact and portable. With its moderate focal length of 500mm and f/4.4 focal ratio, the StarBlast 114mm reflector will display detailed views of the Moon and planets like Jupiter, Saturn and Mars. Brighter galaxies, nebulas and star clusters of deep space are also well within reach of this wide-field reflector telescope. The included StarBlast AutoTracker Mount will automatically track any of these objects once you've aimed the telescope at them, so you can enjoy the view for as long as you wish without having to hassle with re-aiming the telescope as the object appears to migrate across the night sky.

An EZ Finder II reflex sight is included to help aim the telescope, and two included 1.25" eyepieces (10mm and 25mm) provide two different magnifications (50x and 20x) right out of the box. A collimation cap is also included to help periodically align the telescope's reflecting optics. Easily manageable at just 12.4 lbs. when assembled, the StarBlast 114mm AutoTracker Reflector can be taken almost anywhere you want to enjoy views of starry skies with the luxury of automatic tracking.

After completing a simple alignment procedure, the Orion StarBlast AutoTracker Altazimuth Mount's internally housed motors rotate the mount and attached 114mm reflector telescope so the object you're observing will stay centered in the telescope eyepiece (astronomers call this "tracking"). This allows you to enjoy lengthy views of objects in the night sky without having to hassle with moving the telescope manually to keep the object centered. While the StarBlast 114mm AutoTracker Reflector Telescope will not locate objects for you (without the optional Orion Atlas/Sirius Computerized GoTo Hand Controller), it will precisely track any celestial object that has been manually located and centered in the eyepiece. With the luxury of precise automatic tracking, you can concentrate on observing night sky objects, instead of constantly reorienting your telescope as the target object drifts out of your telescope eyepiece's field-of-view. You'll be able to discern more subtle features and details of celestial objects as you relax at the eyepiece without having to worry about manually repositioning the telescope to keep the object in sight.

It's easy to align the StarBlast 114mm AutoTracker. All you have to do is level the mount using the built-in bubble-level and threaded risers on two of the mount feet, set your local latitude, and align the attached telescope to North. Once these simple steps have been completed, all you have to do is turn on the AutoTracker's power switch, and you'll be tracking the heavens automatically! Thanks to an adjustable dual-encoder clutch mechanism, you can aim the reflector telescope manually without the tracking system losing its alignment.

On top of automated tracking, the StarBlast 114mm AutoTracker Telescope also features camera cruising functionality. This allows you to attach a Canon DSLR camera to the Mount using an included L-bracket so you can easily take time-lapse photos, panoramic photos, and even capture snapshots at select positions as the AutoTracker moves the attached Canon DSLR camera. A Canon shutter-release cable is also included for added convenience.

Eight AA batteries are required for motorized operation of the StarBlast AutoTracker Mount; or you can use an optional 12V, 2 amp power supply or AC Adapter (batteries and optional power supplies sold separately). 

You can upgrade the StarBlast 114mm AutoTracker easily to add GoTo object location and pointing abilities by plugging in an optional Orion Atlas/Sirius Computerized GoTo Hand Controller (sold separately). The optional computerized hand controller converts the StarBlast 114mm AutoTracker Reflector into a full GoTo telescope that can automatically find objects in the sky for you!
