Night-sky targets for October 10-17, 2008
The constellation Equuleus, double star Albireo, and Polarissima Borealis are visible in the night sky this week.

Each week, Astronomy magazine Senior Editor Michael Bakich, a master at explaining how to observe, posts a podcast about three objects or events you can see in the sky.
Albireo (Beta 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 (Takahashi TOA-130 refractor and Sbig STL-11000 CCD camera; 60-minute exposure with RGB filters).

In each episode, Michael highlights:
- One object you can see without any optical aid
- One object you can see with a small (4-inch) telescope
- One object you can see with at least an 8-inch telescope
