Observing podcast: Asteroid Juno, open cluster NGC 6716, and globular cluster NGC 6717
September 11-18, 2009, the Asteroid Juno makes a great object for beginning observers, while open cluster NGC 6716 and globular cluster NGC 6717 provide nice targets for telescope owners.

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.
Juno glows brighter than at any time since 2005 when it reaches opposition this month. This modest asteroid — the smallest of the solar system’s “Big Four” — slides southwest through Pisces.

- One object you can see with a small (4-inch) telescope
- One object you can see with at least an 8-inch telescope
