LA CAILLE (DE) (Abbé); Nicolas-Louis; 1713-1762; FRA

From the Cape of Good Hope, he studied the southern sky (still nearly virginal) between 1751 and 1753, he named constellations and discovered some nebulae with his small refractor (0.5-inch). He established the first southern star catalogue containing 9776 stars observed in less than 11 months ("Caelum Australe Stelliferum", published partly in 1763 and completely in 1847), and a catalogue of 42 nebulae in 1755 ("Sur les étoiles nébuleuses du ciel austral", in the "Mémoires de l'Académie Royale des Sciences", 1755) containing 33 true deep sky objects (26 own discoveries).
