Another suggestion, that is simple but I find often overlooked... use your binoculars on the night's sky. Tiny compact spy glass don't offer much, but the big bulky heavy ones really work well to bring more stars and colors to your eyes.
A good pair of big bino's lets you see a few of Jupiter's larger moons, a fuzzy band that is Saturn's rings, and on a night with a partial Moon, you can actually get a little depth perception and the mountains and craters seem to pop out.
If you catch the ISS during a flyby, bino's will let you see the "H" shape created by the huge solar arrays at both ends of the main body of the space craft.
