Object: IC 1275
This image actually contains a number of cataloged objects. IC 1274 is the bright, circular nebula just right of center near the bottom of the image. Up and to its right is a somewhat fainter circular nebula named IC 1275. Between the two is a wide dark lane designated Barnard 91. Above IC 1275 is a bright filament known as NGC 6559. The prominent dark features immediately to its left are Barnard 302 and 303. Above and at an eleven o’clock position from NGC 6559 is a bright knot listed as planetary nebula PK 6-2.1. There is some question as to whether or not PK 6-2.1 is actually a planetary nebula, with a consensus of thought suggesting that it is indeed another type of object and therefore miscataloged. IC 4685 is the general designation for the nebulosity around Barnard 302 and 303.
This nebula complex in Sagittarius lies slightly more than one degree ENE of its more famous neighbor, the Lagoon Nebula.
