In small telescopes, Almach can be easily resolved as a double star, and is a very interesting and beautiful sight for amateur astronomers. The main star (γ¹) is a K3-supergiant of spectral type K3 and a brightness of +2.13 m. The companion (γ²) with a brightness of +4.84 m is 9.6" away at a position angle of 63 degrees. Supergiants are the most massive stars. ... Brightness is an attribute of visual perception in which a source appears to emit a given amount of light. ... // Headline text HEY!! HOW ARE YOU ALL??

Interestingly, γ² itself can be resolved as a double star with much larger telescopes. Its two components are a B8 main sequence dwarf with apparent magnitude of +5.1, and an A0 dwarf with an apparent magnitude of +6.3. They have an orbital period of 61 years. The brighter of these is known to be a spectroscopic binary itself, with an orbital period of 2.67 days. Thus γ² is a triple star.
