The SkyScout is a handheld, battery powered device about 7.4" x 4.0" x 2.5", and weighs about 1 pound. It has a viewing port, a 3" x 1" LCD displayon the side and several buttons for controlling and selecting device functions.
Operation
The SkyScout has a 12 channel GPS receiver and orientation sensors that measure location and pointing angle. From an internal database of some 6,000 celestial objects an object is identified simply by centering it in the device's zero-power optical finder and pressing a button. The LCD screen displays the name of the object and other relevant data. An audio presentation is available via earphones on 200 of the most popular celestial objects. The SkyScout will also locate an object; the user selects the desired object from the database and red arrows in the viewfinder direct the user to point the viewfinder to the object. The SkyScout also features a "Tonight's Highlights" mode, leading the user through the night's best objects.
Expandability
The database can be expanded with extra plug-in SD data cards. A USB connection is also provided for online updates of the object database and device firmware. Since 1 January 2016 the database and firmware can no longer be updated.
Skyscout has been known to scratch easily, and battery life is short at about one-half hour.. The sensors inside of it were far too twitchy around anything metal and made it difficult to use. The advent of iPhone/Android and associated astronomy apps have somewhat eliminated the need for this device. However the Skyscout had a low-intensity light system that allowed users eyes to adapt to the darkness needed for observing stars. Note: the Celestron SkyScout's database of star and planet positions only extended up to Jan 1, 2016. After this date the SkyScout is not supported by Celestron and no longer works as designed. Because the current date cannot be entered, none of the stars are in the positions that SkyScout indicates, although of course the stars remain in the same position for time, date and location. Celestron did not indicate this obsolescence date on the product or in the manual. As of April 7, 2019, the Sky Scout can no longer decode the GPS supplied date and time correctly, because the of GPS week number rollover in 2019.§
