NGC 1712, also known as GC 942, JH 2685, and Dunlop 112 is an open cluster in the constellation of Dorado. [2] [3] It is relatively small, and is located inside the Large Magellanic Cloud. [4] NGC 1712 was originally discovered in 1826 by James Dunlop, although Herschel rediscovered it in 1834. [4] Nine variable stars have been discovered in it so far, with three suspected to be binary systems. [5]

Dorado is a constellation in the Southern Sky. It was named in the late 16th century and is now one of the 88 modern constellations. Its name refers to the mahi-mahi, which is known as dorado ("golden") in Spanish, although it has also been depicted as a swordfish. Dorado contains most of the Large Magellanic Cloud, the remainder being in the constellation Mensa. The South Ecliptic pole also lies within this constellation.
