As we’ve learned, we can easily follow the clockwork motions of the ecliptic and the celestial sphere. Before you think that seems like nothing, ask yourself how many of your friends can tell you what constellations you can see, where the planets are, or why the Moon has phases. You see? You’ve learned so much already that you can even tell from a stick in the ground when we are approaching an equinox!

Once you’ve learned the constellations, so much awaits you. There are many star clusters that can be seen with no special equipment. For example, the three stars in the belt of Orion are known as Collinder 70. The cluster of stars in Taurus is Messier 45—The Pleiades. From a dark sky site you can even see other galaxies and nebulas! All it takes is some practice and knowing where in the sky to look. Besides, there are other terrific things to do. Meteor showers, aurora, occultations, eclipses, and even satellite watching require nothing more than just your attention—knowing when and where to look.
