Description:
I see 15 * inside 8' in NGC6530.
Very faint nebulosity (that's M8) surrounds the cluster, and extends to
the S-SW of its west rim. NW of it is dark lane, extending in NE-SW
direction, that separates it from the moderately bright, 6' long nebulosity
with 2 bright stars (positioned almost S-N), and one somewhat brighter
area to the W-SW of the southern bright star. This brightest area is
1' in diameter.
