[Paal Gulli]

Betelgeuse is one of the easiest stars at the sky to identify.

Find the constellation of Orion, "the hunter." The star that marks the hunter's left shoulder (from your vantagepoint) looks conspicuously red.

That is Betelgeuse. Easy-peasy.

Orion appears “upside-down” when visible in the southern hemisphere.
