The Cup. Best placed in December. It straddles the celestial equator, so it is visible from essentially anywhere on Earth at the right time of year.
Crater, known in English as the Cup, is centred near right ascension 11.7 hours, declination -15°. It straddles the celestial equator, so it is visible from essentially anywhere on Earth at the right time of year.
It reaches its highest point in the sky around local midnight in December, which is when it is easiest to pick out. Earlier in the year it rises before dawn; later, it is already setting in the evening.
SkyRef draws Crater in its real position for wherever you are, right now, along with the other 88 IAU figures.
