The Moon makes a great first target, as it’s close and bright. The lunar surface is crisscrossed with linear features known as rilles, pock-marked with impact craters, and has a good contrast between the brighter uplands and darker maria. Jupiter and its moons, or the rings of Saturn, also make for impressive sights, and if you’re in the northern hemisphere the Andromeda galaxy will blow young minds when you tell them how far away it is and how many stars it contains.
