Photo: Till Credner	Great Square of Pegasus Visible with the naked eye Sep 15 - Jan 15 The Great Square of Pegasus forms the body of Pegasus, the flying horse. The horse flies upside down for most of its path across the sky. Pegasus's hind legs are part of the constellation Andromeda, named for the mythological daughter of Queen Cassiopeia.
Photo: Adam Evans	Andromeda Galaxy Visible with the naked eye Sep 15 - Jan 30 The Andromeda Galaxy is the most distant object (at about 2.5 million light years) that can easily be seen with the naked eye.
Photo: Vzb83	Orion Visible with the naked eye Nov 01 - Feb 01 Look for Orion the Hunter, high in the southern sky. Three bright stars in a line make up his belt. The very bright star to the left of Orion is Sirius, the dog star and the brightest star in the sky, part of the constellation Canis Major, Orion's faithful Big Dog which follows him everywhere.
Photo: Ole Nielsen	Orion Nebula Visible with binocular Nov 01 - Feb 01 The Great Nebula of Orion, or M42, is a huge cloud of hydrogen gas in which young stars are being born. It lies roughly 1.3 light-years away from us. You can find it easily in binoculars. It is the cloud around the middle star (actually four stars, called the Trapezium) in Orion's sword (not his belt).
Photo: NASA, ESA, AURA, Caltech and Palomar Observatory	Pleiades Visible with the naked eye Dec 01 - Feb 01 The Pleiades, or Seven Sisters, is one of the closest star clusters to us. Most people can only see six of the stars with the naked eye.
Photo: Rawastrodata	Double Cluster Visible with binocular Sep 01 - Apr 01 The Double Cluster in Perseus consists of two groups of young stars, with more than 300 blue-white super-giant stars in each cluster. They are easy to see in binoculars, though they are even prettier in a small telescope.
Photo: Till Credner	Cassiopeia Visible with the naked eye Aug 01 - Dec 31 Cassiopeia, named after a queen of Greek mythology, looks like a big letter W in the northern sky. It is a "circumpolar" constellation, which means it is visible all year, but it is highest in winter.
