CaelumCAELUM the Chisel is a very unremarkable constellation, since no stars are brighter than magnitude 4.5. Fortunately for the chisel, there are a couple of galaxies, the most amazing is NGC 1679, located above the two brightest stars in the constellation. Surrounding constellations are Columba, Lepus, Eridanus, and Horologium. Caelum isn't very visible to observers in the Northern Hemisphere, and it probably isn't a spectacular sight in the Southern Hemisphere! Now you know about Caelum!
