Alnair (α Gruis) - The brightest star in the constellation with a visual magnitude of 1.7. Its name means "bright star". It is a blue-white main sequence star 70 times more luminous than the Sun, located 60 light-years away. Among the trio of the brightest stars in the constellation, it is the closest to us. At an angular distance of 28.4", there is a faint companion with a magnitude of 11.8.

β Gru - The red giant irregularly varies in brightness from 2mag to 2.3mag. Its luminosity is approximately 800 times that of the Sun. It is located 200 light years away. In the eyepiece, it nicely contrasts with the blue-white star Alnair.

γ Gru - The blue giant is even brighter than the two previous stars. It is located 230 light-years away from us. Its visual magnitude in the sky is 3.2 mag.

δ Gru - Astronomický text:

A naked-eye distinguishable optical double star. The separation between the yellow 4mag and the red giant 4.1mag is 12 arcminutes. Both components are also doubled. In the first one, we can distinguish a companion with a brightness of 12.8mag at a distance of 5.6".

θ Gru - A physical binary star, whose companions can be distinguished even in a small telescope at a separation of 14 arcseconds. They have magnitudes of 4.5 and 7.

μ Gru - Wide optical double star distinguishable with the naked eye. It consists of yellow giants with magnitudes of 4.8 and 5.1, located at a distance of 260 and 240 light years.

R a S Gru - Variable stars of the Mira Ceti type are observed in their maximum brightness. R Gruis changes its magnitude from 7.4 to 14.9 in a period of 332 days, while S Gruis changes from 6 to 15 over a period of 401 days.
