Alamak (γ Adromedae) - The star is located 350 light-years away. To the north of it lies the radiant of the Andromedids meteor shower. One of the most beautiful double stars in the sky. The primary component is orange and has a brightness of 2.3 magnitude, while the companion is greenish-blue and has a brightness of 5.5 magnitude. It is also a close double star (0.5"), but it is not observable with smaller amateur telescopes (in a larger telescope, it appears as a slightly elongated, blurry star). Its orbital period is 61 years. The angular distance between the primary components of Alamak is 9.8 arc seconds, so we can resolve them even with a small telescope with a 5 cm objective diameter.
π Andromedae - A binary star (with stars of 4.4 magnitude and 8.6 magnitude, angular separation of 35.9'') can be resolved with a small telescope with a 6 cm objective diameter. The primary component has an absolute magnitude of -1.1, is 170 times more luminous than the Sun, and is located at a distance of 600 light-years. In a telescope with a 200mm objective diameter, it appears as a bright white star with a faint bluish companion. A faint star of magnitude 13 is also projected in the vicinity.
36 Andromedae - A tight binary star (components 6mag and 6.4mag with a separation of 0.6"-1.4" over 165 years), which serves as a test for larger amateur telescopes. It is located 124 light-years away. The primary component is a giant many times brighter than our Sun. The companion, on the other hand, is very similar to the Sun. It has the same spectral type and the same color - a beautiful yellow.
R Andromedae - The long-period variable star of Mira Ceti type, the brightest in this constellation. It is located near the small triangle of stars θ, σ, and ρ And. At its maximum brightness of 5.8 mag, it is on the edge of visibility to the naked eye, but over 409.33 days its brightness decreases to 14.9 mag (thus changing by 9 magnitudes) and with smaller amateur telescopes it is practically unobservable. The distance is not precisely determined, approximately 790 light-years.
Groombridge 34 (Grb 34) - The red star, a dwarf from the nearby vicinity, is only 11.56 light-years away and visible even with a small telescope at its 8.2 magnitude, about a quarter of a degree away from the star 26 And. A companion of brightness 10.6 magnitude orbits it at a distance of 35.5" in 2,600 years. The pair has a fast proper motion of 2.89" per year. Detailed drawings made at high magnifications once a year reveal this motion relative to the surrounding star field.
