Compare the view of your nighttime sky to the Magnitude Charts below. This will determine the magnitude of the faintest stars that you can see at your location. For printouts to use during your observation, you can use the magnitude charts included in the Activity Guides. For practice, try the Observation Practice quiz! (requires Flash)
Can You Find Cygnus?
Cygnus the Swan is easy to find as it flies south along the path of the Milky Way. It is easiest to spot by looking straight up and looking for the three brightest stars forming what is known as the Summer Triangle. The bright star in the lower left of this triangle is Deneb, the tail of the swan. By using this star and looking in toward the center of the triangle, you can now spot Cygnus.
