Bright and dark nebulas and open star clusters in Sagittarius and Serpens. This is a close-up of the Small Sagittarius starcloud (Messier 24, at bottom right), with the field extending north to include the nebulas M17, the Swan Nebula, and M16 at top right, the Eagle Nebula. Between M17 and M24 is the small star cluster M18. Patches of red and blue nebulosity at bottom right below M24 are IC 1283 and the blue reflection nebulas NGC 6589 and 6590. The prominent dark nebula at the right (west) edge of the starcloud is Barnard 92 with its lone star embedded in it, with smaller B93 above it. At left are the star clusters M25 (bottom) and NGC 6645, with the large dark nebula B312 above. Taken on August 17, 2020.
