This is the southern equivalent to the Messier Catalogue.
"In
Southern Gems, Stephen James O'Meara makes a detour beneath the southern skies, presenting a fresh list of
120 deep-sky objects for
southern hemisphere stargazers to observe. Showcasing many exceptional objects
catalogued by the pioneering observer James Dunlop, known as the
'Messier of the southern skies', all are visible through small-to moderate-sized telescopes or binoculars under dark skies."
