ζ Her - A nice double star in the "Flowerpot". The components have magnitudes of 2.9mag and 5.5mag and are approximately 1.6" apart. Since their orbital period is only 34.5 years, the positional angle and separation change rapidly.
δ Her - A well-known optical double star, whose pale blue components exhibit completely different proper motions, resulting in a relatively significant change in their mutual position over time. In 1830, their mutual separation was 26", but by 1960 they had approached each other to a distance of only 9", and since then their separation has gradually increased again. The primary star has a magnitude of 3.1 and the companion has a magnitude of 8.2. To resolve this rare pair, a telescope with a 6 cm objective diameter will suffice.
μ Her - The main and conspicuously yellow component with a brightness of 3.4 magnitude has a companion of 10th stellar magnitude, which is actually composed of two red dwarfs.
Ras Algethi (α Her) - A significantly red star is located near the border with Hadonoš, a supergiant whose brightness irregularly varies between 3.1 mag and 3.9 mag, often only between 3.3 mag and 3.7 mag. The period is 90 to 100 days. Suitable comparison stars are ι and κ Ophiuchi, which are located about 6.5 degrees to the southwest and have a brightness of 4.3 mag and 3.2 mag, respectively. Alpha Herculis is also a binary star, with its second component of fifth magnitude located 4.7" away, visible even in small telescopes with a 6 cm objective diameter. It has a greenish tint that nicely contrasts with the red giant.
68 Her - An eclipsing binary star. They are actually two strongly flattened, almost equally sized stars that orbit each other in 2.051 days. As a result, we observe light changes of 68 Her from 4.7 mag to 5.4 mag. The brightness of both stars is quite different. The brighter one is 260 times more luminous than the Sun and the weaker one is only 100 times. Their mass reaches 7.5 times and 2.9 times the mass of the Sun. In terms of size, both stars exceed the diameter of the Sun by about 6 times.
Marfak (κ Her) - A physical binary star, whose yellow components with magnitudes of 5.3 and 6.5 are separated by 28.4", and therefore can be resolved even in small telescopes. 36" to the SSW there is another companion with a magnitude of 13.6.
36/37 Her - Two ordinary close stars, which can be distinguished even with a hand lens. They are located on the southwestern edge of the constellation at a mutual distance of 70" and their brightness is 5.7 mag and 6.8 mag, respectively.
