Corwin's Notes
=====
NGC 6523 is the star-forming core of M 8 at the heart of the bright
northwestern part of the nebula. NGC 6526 (which see) is the southeastern
part of the nebula, and NGC 6530 is the bright star cluster 10-12 arcmin
following N6523. NGC 6533 (which see) applies to the entire M 8 complex, and
IC 1271 and IC 4678 (both of which see) apply to condensations in its eastern
reaches.
Steve's Notes
=====
NGC 6523
17.5" (6/6/86): extremely bright, detailed nebulosity that nearly fills a 50' field. Extensive fainter nebulosity fills the region to the north and a thin extension is to the east. Cut by a large high contrast dark lane ("Lagoon") oriented SW-NE. The brightest luminary within the nebula is 9 Sagittarii (V = 6.0), situated to the west of the dark lane with a mag 7 companion 3' NNE. A very bright 30" nebulous knot ("Hourglass Nebula", ionized by O7 star Herschel 36) is situated 3' SW of 9 Sagittarii. NGC 6530, a bright open cluster, is on the east side of the dark lane. Barnard 89 is a fairly well-defined roundish dark nebula ~6' following NGC 6530. The Lagoon is a prominent naked-eye object in dark sky. See observing notes for NGC 6530 and IC 1271. The Trifid Nebula (M20) lies 85' NNW.
