My friend has a telescope that I think is controlled with a motor. Does this kind of telescope have to be hooked up to a computer or something. Were going out to look at mars and I don't really know anything about setting up telescopes or anything. What kind of computer program would I need and is there a nice website out there that shows whats in the sky in my area at any given time and how to find it. I was looking at the sky chart at www.heavens-above.com and I'm not sure if thats it.
