Messier 23, also known as NGC 6494, is an open cluster of stars in the northwest of the southern constellation of Sagittarius. It was discovered by Charles Messier in 1764. It can be found in good conditions with binoculars or a modestly sized telescope. It is in front of "an extensive gas and dust network", which there may be no inter-association. It is within 5° the sun's position so can be occulted by the moon.
16 Arietis is a star in the northern constellation of Aries. 16 Arietis is the Flamsteed designation. Its apparent magnitude is 6.01. Based upon the annual parallax shift of 6.27 ± 0.07 mas, this star is approximately 520 light-years distant from Earth. The brightness of this star is diminished by 0.40 in magnitude from extinction caused by interstellar gas and dust. This is an evolved giant star with a stellar classification of K3 III.
82 Cancri is a solitary, orange-hued star in the zodiac constellation of Cancer.

This is a pulsating Mira-type variable star with a brightness varies from magnitude +4.4 down to +13.5 with a period of 433.6 days. At its maximum, R Cassiopeiae is visible to the naked eye as a faint, red-hued star.
HD 13189 is an 8th magnitude star in Triangulum constellation.
HD 221776 is a double star in the northern constellation of Andromeda. With an apparent visual magnitude of 6.18, it is viewable by the naked eye user very favourable conditions. The most luminous component has a spectral classification K5III, meaning that it is an orange giant star that has evolved off the main sequence. An infrared excess has been detected around this star, indicating the star is associated with a cloud of dust particles.
HD 221246 or NGC 7686 1 is a star in open cluster NGC 7686, and it belongs to the northern constellation of Andromeda. With an apparent visual magnitude of 6.17, it can be viewed by the naked eye only under very favourable conditions. It has a spectral classification of K3III, meaning it is an evolved orange giant star. Parallax measurements place this star about 1,000 light years away from the solar system.
HD 223311 is a star in the equatorial constellation of Aquarius. It has an orange hue and is visible to the naked eye as a dim star with an apparent visual magnitude of 6.08. Based on parallax measurements, the star is located at a distance of approximately 910 light years from the Sun. It is a radial velocity standard star that is drifting closer to the Sun at the rate of −20 km/s. The star is situated near the ecliptic and thus is subject to lunar occultations.
HD 128198 is a giant star in the northern constellation of Boötes.
HD 32518 is a solitary star in the northern circumpolar constellation Camelopardalis. It has an apparent magnitude of 6.42, placing it near the max naked eye visibility. Located about 400 light years away, it is receding with a heliocentric radial velocity of −7.02 km/s.
HD 102350 is a single star in the constellation Centaurus. It has a yellow hue and is visible to the naked eye with an apparent visual magnitude of 4.11. The distance to this star is approximately 390 light years based on parallax, but it is drifting closer with a radial velocity of −3 km/s. It has an absolute magnitude of −1.51.
HD 96819 is a single star in the equatorial constellation of Hydra. It was formerly known by its designation 10 Crateris, but that name fell into disuse after constellations were redrawn and the star was no longer in Crater. It is visible to the naked eye as a dim, white-hued star with an apparent visual magnitude of 5.43. Parallax measurements put it at a distance of 182 light years away from the Sun. This is most likely a member of the TW Hydrae association.
Sigma Ophiuchi, Latinized from σ Ophiuchi, is a single, orange-hued star in the equatorial constellation Ophiuchus. Its apparent visual magnitude is 4.31, which is bright enough to be faintly visible to the naked eye. The annual parallax shift of 3.62 mas as seen from Earth provides a distance estimate of roughly 900 light years. It is moving closer to the Sun with a radial velocity of −28 km/s.
ν Pegasi, Latinized as Nu Pegasi is a single star in the northern constellation of Pegasus. It is an orange-hued star that is faintly visible to the naked eye with an apparent visual magnitude of 4.84. The star is located approximately 261 light years away based on parallax, but is drifting closer with a radial velocity of −19 km/s.
HD 111456 is a yellow-white hued star in the northern circumpolar constellation of Ursa Major. It is dimly visible to the naked eye, having an apparent visual magnitude of 5.85. Based upon an annual parallax shift of 38.2 mas as seen from Earth, it is located about 85 light years from the Sun. The star is moving closer to the Sun with a radial velocity of −18 km/s. HD 111456 is a nucleus cluster member of the Ursa Major Moving Group, a set of stars that are moving through space with a similar heading and velocity. Six other stars in the nucleus of the group are prominent members of the Big Dipper asterism.
HD 30479 is a solitary star in the southern circumpolar constellation Mensa. It has an apparent magnitude of 6.04, making it barely visible to the naked eye even under ideal conditions. It is located at a distance of 540 light years but is receding with a heliocentric radial velocity of 10.3 km/s.
HD 193472 is a solitary star in the equatorial constellation Delphinus. It has an apparent magnitude of 5.94, making it visible with the naked eye if viewed under ideal conditions. Parallax measurements put it at a distance of 282 light years and has a radial velocity of −8 km/s, indicating that the object drifting towards the Solar System.
HD 37289, also known as HR 1916, is a solitary, orange hued star located in the northern circumpolar constellation Camelopardalis. It has an apparent magnitude of 5.61, making it faintly visible to the naked eye under ideal conditions. Based on parallax measurements from the Gaia spacecraft, the object is estimated to be 308 light years distant. It appears to be approaching the Sun, having a heliocentric radial velocity of −20.7 km/s.
