Observation 2 9/20/10

Today at the stargaze we saw many different celestial objects. We saw 6 1st magnitude stars, Antares, Altair, Deneb, Vega, Fomalhaut, and Arcturus. We also saw the planets Venus, Mars, and Jupiter. We watched Venus set below the horizon and it turned a bright red right before it went down. Also, we were able to see 4 moons orbiting Jupiter; Io, Europa, Callisto, and Ganymede. Some of the constellations that we saw were Sagittarius (and the Teapot), Scorpius, Aquila, the Summer Triangle, Scutum, Hercules and the Keystone, and the Little Dipper. We could also barely see various M objects with the binoculars because the moon was in its waxing gibbous phase so it blocked out dimmer sources of light.
