Podcast: Night-sky targets for July 31-August 7, 2009
This week, Small Sagittarius Star Cloud makes a great object for beginning observers, while the open cluster NGC 6738 and the dark nebula Bernes 157 provide nice targets for telescope owners.

 The Small Sagittarius Star Cloud spans nearly 2° and measures 0.6° wide, so it's not likely that anyone would confuse it for a comet. Still, Messier cataloged this region, and we now refer to it as M24.
