Kaus Australis (ε Sgr) - The brightest star of the constellation (1.85mag) is located in the southern part of the arc and reaches a maximum height of 7 degrees above the southern horizon at its culmination. It has a white color. It shines as bright as 250 Suns from a distance of 125 light years. It is also an optical double star, with a companion of seventh magnitude located about 3.3 arc minutes to the northwest, which can also be observed with a telescope.

η Sgr - Easily observable double star: the magnitudes of the components are 3.2 and 7.8 and they are located at distances of 3.6". The brighter component is red-orange, while the fainter one is white. At a distance of 93", there is a 10th magnitude star, and at a separation of 33", there is a 13th magnitude star.

Arkab (β Sgr) - Wide optical double star suitable for observation with a refractor. The primary component has a magnitude of 3.9, and additionally, there is a companion of magnitude 8 located at a distance of 28.4".

21 Sgr - unequally bright and contrasting double star of orange (4.9mag) and bluish components (7.4mag), which are separated by only 1.8", so they cannot be easily distinguished with a small telescope.

54 Sgr - The beautiful triple star is easily distinguishable in small telescopes. The brightest component is dark yellow (5.4 mag), the second one is pale blue (11.9 mag), and the third one is yellowish (8.9 mag). The separation of the AB pair is 38", and the separation of the AC components is 45.6".

RY Sgr - The equivalent of R Coronae Borealis, because it suddenly and unexpectedly changes its brightness from the eighth to the fourteenth magnitude. It does not have any precise period, and after R Coronae Borealis itself, it is the brightest star of this type. Its brightness unexpectedly decreases when carbon soot accumulates in the atmosphere.

W a X Sgr - Cepheids, which change their brightness with a weekly period from the fourth to the fifth magnitude. X SGR is located near the border with the constellation of Sagittarius. It reaches a maximum of 4.3 mag and a minimum of 4.9 mag. Its period is 7.012 days. W SGR fluctuates between 4.3 mag and 5 mag in a period of 7.595 days.

Herschel 5003 - A triple star consisting of two red-orange stars, with the brighter one at 5.2 magnitude being redder. The fainter one at 6.9 magnitude is located at a distance of 5.5". Another, very faint companion at 13 magnitude can be found at a distance of 26.2" and can be resolved during a good night. These triple stars are located in a beautiful field of the Milky Way.
