Get a DOBSONIAN with a large opening, like one of the Skywatchers

or the 8" version. ANY serious amateur astronomer will agree with me on that.
Reasons:
For astronomy, nothing is more important than the aperture ("size of the lens") or in this case the mirror diameter. The larger the diameter, the more light the scope can collect, the more details you can see. ("Magnification" is pretty much non important)
A DOBsonian telescope is where all investment is in the optics, and not with gimmicky stuff like a computerized "GoTo" mount. Say, if you were to spend $300-$500 on a fancy "Goto Scope", you will pay most of it for the computerized mount and remote and get some crappy or small optics thrown in.
IF you have a ton of money to spend, then get a 6" or 8" Celestron/Meade with a fancy GoTo mount...but if you're on a budget get a 6" or 8" Skywatcher (or Orion, GSO or whatever brands there are) where the optics will be on par - and this is what counts. (Skywatcher, Orion, GSO etc...are all manufactured in China and their optics may even be all the same, but astronomers agree that the quality of the optics is good for the money and differences between those brands are rather minimal.)
So..once you decided on your telescope (and I highly recommend a DObsonian like the above) you ALSO want some additional eyepieces. The included ones are often "mediocre" and most of the time it will only come with two or so. So get a set of eye pieces like a wide-angle one and a planetery eye piece and maybe a zoom eyepiece as well.
