...the majority of times you are better off with a powerful pair of binoculars!
I am not too hot on telescopes myself, but I was advised to use a pair of binoculars, and I got the chance to see the Galilean moons of Jupiter, well actually only Ganymede, Europa and Callisto (Io was obscured by the brightness of Jupiter); hey, but three outta four ain't bad!
I think it's amazing that I can peer at the same objects that Galileo looked at, it's kinda corny, but I do feel a kind of connection. I imagine what it would of been like to observe the orbiting moons of Jupiter six-hundred and twenty-eight million kilometres away. The first member of the human species to glimpse a view of the dance of matter. Hunks of rock orbiting the immense Jupiter for innumerable millennia; almost destined to be discovered by a curious mind. Waiting to be discovered, explored and experienced. Nature is beautiful, and science gives us the chance to observe a glimpse of this beauty and intricacy. How depressing it would be if we stagnated in our churches worshiping an alter when the universe is filled with breathtaking, uncomprehendable awesomeness.
People criticise investment in space as a waste of money, although we've gained more money than we've spent, I would not be bothered at all if we didn't earn back a penny because what we've gained is perspective; we are simultaneously insignificant and irrelevant and extremely unique and valuable. The universe doesn't end at the edge of our atmosphere, it only begins.
