Nathan, yes to all your questions. I shot the ISS hand held when it was visible (I'd used a program to tell me what it was going to be visible for me). I focused manually and rattled off shots in burst mode. It was hard to see detail on it, but comparing it in each shot it changed its angle and was obviously man made.

Satellites are often problematic to astrophotographers. Taking long exposures of the sky (10 sec or more) and its a good chance you'll find one or more in your shots as they make lines which stand out. Simple rule of thumb, if its blinking as it moves its a plane of some type (satellites dont have blinking lights). Satellites can be very bright as they reflect the light of the sun and move steadily in one direction, shooting stars are meteors burning up in the atmosphere and move very fast, they flare up and dim quickly.

Combining shots? yes. Nebulae are typically large in the sky but faint, by combining shots you can bring them out. BBCs Stargazing Live a few years back did this for viewers, asked people to take photos of the Orion constellation with whatever cameras they had, be it DSLR or mobile phone and sent them in to the show where they were all combined in order to reveal the amazing Orion Nebula.

Takes a bit of work but where there's a will there's a way.
