After an initial dabble with a home made (which I was very chuffed with) adaptor to fit commercial eyepieces to a camera lens, I was very much drawn to getting a proper telescope. The camera lens I had was a 500mm telephoto (mirror lens) - which despite being a genuine Nikon wasn't very expensive and the set up worked quite well. Suitably inspired I bough a very high quality "apo" 4" refractor. Even from the city, jupiter with its moons and stripes, or saturn's rings are easily seen, and the moon is just spectacular. Orion Nebular, or milky way star fields likewise. As others have said, seeing these things with your own eyes is thrilling. Only used it casually, and not all that often but glad I've got it. Maybe a couple of grand's worth so I haven't skimped, nor gone crazy either.
A final thought is seeing pictures in astronomy magazines looking very like pictures in books I had as a kid taken from the Mount Palomar 200" telescope ... but the modern picture were taken from someone's garden in Kent. OK they've got kit worth the price of a modest brand new car, but still astonishing
