In addition to the sky sights mentioned in the August column, I hope you’ll enjoy exploring the following binocular targets in and around Sagittarius this month.

The emission nebula M17, also known as the Omega Nebula and Swan Nebula, is located about 5,000 light-years away, observable with binoculars in the constellation of Sagittarius.

In late May, David Trapani imaged the nebula from Waldwick, New Jersey.

Equipment used: Orion ED80 refractor and Canon Digital Rebel 350XT camera

NGC 6603 can be just glimpsed in 10x and higher binoculars as a small, dim glow just northeast of M24’s center. Its stars are no brighter than about 10th magnitude.

Barnard 92 is a terrific dark nebula to view from a dark site. Look for a small black “hole” (not a real black hole!) silhouetted against the northwest corner of M24.

M17: From the “kite” inside M24, look to the north for a slender, south-pointing triangle of dim stars. M17, the famous omega nebula, is just to the triangle’s east.

M16, better known as the eagle Nebula, is north of M17, across the border into Serpens Cauda. My 10×50 binoculars show about a dozen stars here, all belonging to the Eagle’s associated star cluster, and just the slightest hint of the nebulosity that makes this such a spectacular sight through large telescopes.
