Earlier tonight, my Dad and I were outside with our telescope and computers, getting ready to view Mars.
Our Celestron telescope always needs to pinpoint two large objects--like stars, or clearly visible planets--in order to be able to zoom in on specific objects in the system files. However, getting to the point of "zooming to planets" requires that you go through the process of finding two-three other objects in the sky to help it figure out where it is...
Bottom line: I went on the market and download Google Sky and within 10 minutes, we were focusing in on Mars and capturing videos of it...Close enough that we could even see the ice caps! Having my Droid handy saved us, what is usually, hours of time and let us enjoy ourselves even more. My girlfriend, dad, mom, and I all had a great time viewing the stars for longer than usual.
