A binary star located 3° northwest of Antares, consisting of blue components with magnitudes of 5.3 and 6, separated by 3.1" (4.59 mag). The area around them is interesting for photographers. To the west, there is an elongated dark nebula Barnard 42, which appears as a silhouette against the beautiful gas and dust complex IC 4604, illuminated by the star ρ Ophiuchi. However, the nebula has a very low surface brightness.
