Description:
In Serpens Cauda, at ~ 6¼° SE of Nu Oph. Beautiful diffuse nebula, whose dimensions are easily appreciable at 9x, in spite of its low height above the horizon. The size of M16 are rather well defined and the object is rectangular in form. At the center of M16, a small star cluster is, which 4 more brilliant stars form a parallelogram. These stars are HD 168137, TYC 5689-607-1, TYC 5689-881-1 and HD 168183. The averted vision does not improve much the aspect of the nebula.
