Taken early in the morning at 2am, the constellation of Scorpio is seen here setting behind a ridge line of scrub and rock. Below is an annotated copy of the image showing the rough figure of the scorpion as drawn by joining the bright stars in Scorpio. The claws of the scorpion are already below the horizon.
Scorpio is one of the more easily recognised constellations, and in fact is easier to recognise in person under a medium-dark sky than in a picture I find. Photographs tend to bring out all the millions of fainter stars which makes isolating the brighter primary stars of the constellations harder than it is actually in real life.
