Glenn Chaple's observing basics: Gettin' shapes

October 2004: Are you in shape to go outside tonight and view the shapely sky objects I'm featuring this month?
Are you in shape to go outside tonight and view the shapely sky objects I'm featuring this month? I'm talking about the classic geometric shapes formed by stars in the night sky — you know — squares, circles, and so on. Some are entire constellations, like Triangulum the Triangle. Others are either asterisms, or parts of constellations, exemplified by the "Circlet" of Pisces. A sky shape may even be made up of stars from two different constellations.
