β Scorpii

Beta Scorpii (Graffias or Akrab) is eight degrees northwest of Antares (about one and a half fields of view). It forms a distinctive asterism with its neighbours: binoculars.

Beta is a fine double star with faint companion (BU 947), a blue primary and white companion, AB: 2.6, 10.6; 171º, 0.3".

In the same field is nu Scorpii, a triple system (BU 120):
      AB: 4.4, 5.3; 3º, 1.2".
      AC: 4.4, 6.6; 336º, 41.2".

Move delta Scorpii to the western edge of your field of view: binoculars; about four degrees east of delta is M80.
      M80 is quite small in appearance but a very bright globular cluster, with an apparent magnitude of 7.9. Several hundred thousand stars are compacted into a dense core; in fact it is one of the most dense clusters known. Large telescopes are necessary to begin to resolve its members, which include a large number of ‘blue stragglers’ which gives evidence to a high number of collisions at the core.

Back up to beta, now two binocular fields north brings you to xi1,2 Scorpii.
      Xi Scorpii is a notable multiple star system (Struve 1998):
      AB (two golden stars): 5.2, 4.9; 188º, 0.9" with an orbit of 45.69 years.
      AC: 5.2, 7.3; 89º, 6.9".

Struve 1999 is also gravitationally bound to this system:
      AB (two yellow stars): 7.2, 8.1; 98º, 11.9".
      AC: 7.2, 11.4; 84º, 83.7".
