The constellation Equuleus, the double star Albireo, and Polarissima Borealis (NGC 3172)
October 11–18, 2012: The constellation Equuleus is an excellent target
for naked-eye observers, the double star Albireo in Cygnus offers
small-telescope owners nice views, and large-telescope owners can seek
out Polarissima Borealis (NGC 3172) in Ursa Minor.

Each week, Astronomy magazine Senior Editor Michael E. Bakich, a
master at explaining how to observe, posts a podcast about three or more
objects or events you can see in the sky.
Albireo (Beta [β] Cygni) is a 3rd-magnitude double star in the constellation Cygnus. Albireo A, a golden-yellow star, is itself a double star, but its companion is too close to be observed. Albireo B is a fainter blue star.
