Don't EVER buy a department store telescope. I said it earlier and will say it again. Some components are cheaply made of plastic, the mountings wobble, the finder scopes (used for pointing the telescope to the object) are close to useless, and generally a very frustrating experience. Whats worse, is that even experienced observers find them difficult to use. The only thing they can be used for, is to look at the moon. This will then get you hooked and make you want to buy a better scope. Many of us started out with these telescopes, and after a month or two, learned our lesson and got real telescopes that we've kept and used for years.!

I have no idea in what to look for but here's what I want :
1) Get to see GOOD sharp images of craters etc. on the lunar surface.
2) Decent view of the Rings of Saturn, moons of Jupiter, Mars etc.
3)Be able to see large/medium galaxies in a decent sharp image.
4) Upright image (I've heard some scopes give inverted/mirror images?)
So what are the technical specifications I need to looks for?
