25cm f/5 Astrograph
Extended N and S, 2'.7 x 0'.5, in M 8. There are other well-known markings in this nebula. This one and B 89 are given as illustrations of dark markings in the sky shown in a relief against a nebulous or other luminous background. In this case these may be non-luminous opaque parts of the nebula itself."
