Finding it

Orion, known in English as the Hunter, is centred near right ascension 5.6 hours, declination +13°. 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 September, 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.
