Description
The new, larger aperture ETX-80AT-TC with built-in Barlow lens is powerful companion for exploring the universe at an incredibly attractive price. For the casual observer interested in viewing the Moon, planets, bright deep-space objects, and terrestrial landmarks, the ETX-80AT-TC maybe the perfect instrument.
The #494 Autostar computer system with integrated, factory calibrated time chip, permits the automatic location of over 1400 celestial objects. Just enter the object you wish to observe on to the Autostar display, and press GO TO.
This model replaces the ETX-70AT. Besides a larger 80mm aperture objective lens, the ETX-80 mount/ fork-tines appear larger and more substantial. Significantly, this new model includes a clock-chip for keeping precise time and date no need to ever call again for precise time to set Autostar. The scope is also supplied with a new bubble-level/ compass for fast initialization of the telescope as to level and north orientation. The new model includes two Super Plossl eyepieces (SP9.7 and SP26). |

Additional Features of the ETX-80 |
|
Flip-Mirror System:
For observing in the standard 90° position, flip the internal, optical flat mirror "up." For terrestrial observing with the optional #933 45° Erecting Prism or for photography with the optional #64ST T-Adapter, flip the mirror "down." |
|
Ultra portable and Simple to Use:
Easy to carry to any observing location, whether a distant mountain top or your own back yard, the Meade ETX-80AT telescope brings the excitement of astronomy to users of any age. |
|
Just place the telescope on any flat surface (or use the standard-equipment field tripod), do a quick, easy alignment of the telescope's computer to the sky, and start observing. Six internal (user-supplied) AA-batteries power the ETX-80AT for about 20 hours. |
|
Included as standard equipment with the ETX-80AT, the #494 Autostar controller permits the automatic location of over 1400 celestial objects, including all of the objects located in the telescope's onboard database. |
|
Just enter the object you wish to observe on to the Autostar display, press GO TO, and watch as the telescope moves rapidly in seconds to place the object in the telescope's field of view. |
|
One observing session validates the prediction made by Sky & Telescope that "The ETX/Autostar concept will go down as the greatest happening in amateur astronomy yet." |
|
Objects stored in the #494 Autostar's database include the entire range of celestial phenomena and are designed to keep the active observer busy for many a starlit evening. |
|
The above database listing has been specifically chosen as suitable for observing with the ETX-80AT and provides an excellent introduction to the diversity of astronomical objects visible through the telescope. |
|
In addition to its object-locating capabilities Autostar permits pushbutton centering of objects within the telescopic field at any of nine selectable speeds. Once Autostar locates an object, it directs the telescope automatically to track the object across the sky, compensating fully and precisely for the effects of the Earth's axial rotation. |
