ψ Aqr - The main star with a brightness of 4.5 mag has a companion of 9.4 mag at a distance of 49". In a 10cm telescope, it appears as a wide, unevenly bright pair consisting of an orange and greenish component, resembling the planet Uranus. Very nice color contrast.
Dzeta Aquarii (ζ Aqr) - The well-known binary star in the Aquarius constellation. The two almost equally bright components with magnitudes of 4.3 and 4.5 have a period of mutual orbit determined to be 856 years. In 1967, the stars were only 1.7" apart, but since then their separation has slowly increased. In 1985, it was 1.8", but at the beginning of the third millennium, we perceive them as a yellow to white pair, approximately two arc seconds wide, easily distinguishable even with a small telescope with a 5cm objective diameter. In the year 2160, their separation will increase to 6". The system is located 92 light-years away.
94 Aqr - An easily distinguishable and beautiful double star, composed of two components with magnitudes of 5.3 and 7.3, separated by 12.7", so even a small telescope is sufficient for resolution. One has a nice reddish-yellow hue and the other has a light green shade.
41 Aqr - A binary star composed of two components with the same brightness of 7.1 mag at a separation of 5". In the field of view of a telescope with an objective diameter of around 20 cm, it appears as a tight, equally bright pair of golden and blue components.
53 Aqr - Multiple star. In a 200 mm telescope, a close pair (3.1") of two yellow stars (6.4mag, 6.6mag), which are not related at all - they are just an optical double star. Nearby, two fainter stars are also visible, with magnitudes of 12.9mag and 13.9mag.
R Aqr - Variable star, whose magnitude can sometimes reach a value of up to 5.8mag, although it is usually much fainter. It exhibits rapid, unpredictable fluctuations.
