If you have a clear night and not much light pollution (like I currently do in the UP), you can spot the International Space Station with the naked eye. NASA publishes a schedule of up-to-the-minute sighting times here. It looks like a bright, quickly moving star without magnification, taking 1-4 minutes to pass overhead. With magnification, it’s possible to capture an impressive level of detail. A cool thing to notice if you look up at the right time.
