features of interest epsilon (e) lupi 5 A 3rd-magnitude star with a companion of 9th magnitude that becomes visible with small telescopes.

Kappa (k) lupi 5 A double star with components of 4th and 6th magnitudes that are easily divided with small telescopes.

MU (m) lupi 5 An interesting multiple star. Small telescopes show a 4th-magnitude star with a wide 7th-magnitude companion. The primary star is itself a close double, requiring apertures of at least 4 in (100 mm) to separate.

pi (n) lupi 5 A double that can be divided into matching blue-white 5th-magnitude components with apertures of 3 in (75 mm).

NGc 5822 K 5 A large open cluster close to the southern boundary of the constellation, visible through binoculars and small telescopes.

MU lupi

The two principal components of Mu (m) Lupi—the primary star of magnitude 4.3 (center) and its wide companion star—are clearly visible in this photograph. But the magnification is not great enough to divide the primary star and its closer companion.

open cluster NGc 5822

This scattered cluster (left) can be made out with binoculars and small telescopes against the background of the Milky Way. However, its brightest stars are of only 9th magnitude, so it is not particularly prominent. This photograph shows it as it appears through a small telescope.
