MySky technology - Jun 18, 2007

How do they do it? How do star locaters like the Celestron SkyScout and the new Meade MySky find and identify objects in the sky for you? Seems hard to believe that you can just point an instrument at one of the many hundreds of stars visible in the night sky on any given night and getting an identification. The answer is basically GPS and a software star map data base that knows what the sky should look like on any given time, date and location. First, the GPS provides the MySky with your exact location and time, same as any GPS model. Once the MySky has the location and time, it then produces a map that is correct for your position and time. Finally, when you aim the MySky, sensors detect the exact object in its sights and you get an identification. Sounds simple. It's not. Everything must be coordinated and working properly to get the job done, but when it works, it is truly amazing.
