Sigma Tauri is the Bayer designation for a pair of white-hued stars in the zodiac constellation of Taurus. The system is a visual double star, whose components are designated σ1 Tauri and σ2 Tauri, with the latter being the more northerly star. The two are separated by 7.2 arcminutes on the sky and can be readily split with a pair of binoculars. They have apparent visual magnitudes of +5.07 and +4.70, respectively, which indicates they are both visible to the naked eye. Based upon parallax measurements, σ1 Tauri is about 147 light years from the Sun, while σ2 Tauri is 156 light years distant.
Chi Aquilae is the Bayer designation for a binary star in the equatorial constellation of Aquila, the eagle.

Delta Columbae is a binary star system in the constellation Columba. It can be seen with the naked eye having an apparent visual magnitude of 3.85. The distance to this system, based upon an annual parallax shift of 13.94 mas, is around 234 lightyears.
Nu Herculis, Latinized from ν Herculis, is a binary and variable star in the constellation of Hercules. With an apparent magnitude of about 4.4, it is faintly visible to the naked eye. Parallax measurements made by the Hipparcos spacecraft put it at a distance of about 860 light years.
41 Cygni is a single star in the northern constellation of Cygnus, located near the southern border with Vulpecula. It is visible to the naked eye as a faint, yellow-white hued star with an apparent visual magnitude of 4.02. The star lies at a distance of around 770 light years from the Sun, based on parallax, and is drifting closer with a radial velocity of −18 km/s.
45 Draconis is a single star located in the northern circumpolar constellation of Draco, around 3,500 light years from the Earth. 45 Draconis is the Flamsteed designation, while it has the Bayer designation of d Draconis. This object is visible to the naked eye as a faint, yellow-white hued star with an apparent visual magnitude of 4.78. Radial velocity measurements indicate it is moving closer to the Sun at the rate of −12.5 km/s.
145 G. Canis Majoris is a single K giant or supergiant star in the southern constellation of Canis Major. This star is Gould's 145th of Canis Major in his Uranometria Argentina. Kostjuk erroneously lists it as simply "145 CMa". SIMBAD follows this error in its object query result as "* 145 CMa – Star".
F Hydrae, also known as HD 74395, is a star in the constellation Hydra with an apparent magnitude is 4.64. It was catalogued as 31 Monocerotis, but this name is now rarely used since the star is now within the boundaries of Hydra. It is a low mass yellow supergiant around a thousand times brighter than the sun and five times as massive.
c Puppis, also known as HD 63032 and HR 3017, is a spectroscopic binary star in the constellation Puppis. Its apparent magnitude is of 3.61, making it the eight-brightest star in Puppis. The system is the brightest member of the open cluster NGC 2451, over two magnitudes brighter than every other star in the cluster. As the turnoff point of the cluster is currently around B7, the parameters of the system fit with cluster membership.
η Lupi, often Latinised as Eta Lupi, is a probable triple star system in the southern constellation of Lupus. It is visible to the naked eye with an apparent visual magnitude of 3.41. Based upon an annual parallax shift of 27.80 mas as seen from Earth, it is located around 136 parsecs (440 ly) distant from the Sun. It is a member of the Upper Centaurus–Lupus subgroup of the nearby Sco OB2 association.
Pi5 Orionis (π5 Ori, π5 Orionis) is a binary star system in the constellation Orion. It has an apparent visual magnitude of 3.69, which is bright enough to be visible to the naked eye on a clear night. Based upon an annual parallax shift of 2.43 mas, it is around 1,300 light-years distant from the Sun.
Zeta1 Lyrae, Latinized from ζ1 Lyrae, is a binary star in the northern constellation of Lyra. Based upon an annual parallax shift of 20.89 mas as seen from Earth, the pair are located about 156 light years from the Sun. It is visible to the naked eye with an apparent visual magnitude of 4.37.
Epsilon Normae, Latinised from ε Normae, is a blue-white hued triple star system in the southern constellation of Norma. It has an apparent visual magnitude of 4.47, which is bright enough to be seen with the naked eye. Based upon an annual parallax shift of 6.15 mas as seen from Earth, the system is located around 530 light years distant from the Sun. At that distance, the visual magnitude is diminished by an extinction factor of 0.21 due to interstellar dust.
Omicron1 Orionis is a binary star in the northeastern corner of the constellation Orion. It is visible to the naked eye with an apparent visual magnitude of 4.7. Based upon an annual parallax shift of 5.01±0.71 mas, it is located approximately 650 light years from the Sun. At that distance, the visual magnitude of the star is diminished by an interstellar absorption factor of 0.27 due to intervening dust.
9 Pegasi is a supergiant star in the constellation Pegasus. Its apparent magnitude is 4.35.
HD 59612 is a class A5Ib supergiant star in the constellation Puppis. Its apparent magnitude is 4.86 and it is approximately 4,300 light years away based on parallax.
HD 85622 is a binary star system in the southern constellation of Vela. It is visible to the naked eye with an apparent visual magnitude of 4.58. The distance to HD 85622 can be estimated from its annual parallax shift of 4.3 mas, yielding a value of 750 light years. It is moving further from the Earth with a heliocentric radial velocity of +8 km/s.
HD 25291, also known as HR 1242, is a solitary, yellowish-white hued star located in the northern circumpolar constellation Camelopardalis. It has an apparent magnitude of 5.12, making it one of the brighter members of this generally faint constellation. The object is relatively far at a distant of approximately 2,100 light years but is drifting closer with a heliocentric radial velocity of −20.3 km/s.
