Pegasus, the winged horse, can be seen at the southern middle sky in autumn, and is conspicuous constellation that includes the "Great Square of Pegasus".
All of four stars are generally second or third magnitude, but the vast asterism is fairly obvious because the bright stars hardly can be found around this field.
The each side of the square is nearly parallel to each direction, so it's a good guide to identify the other constellations in autumn skies. The Pegasus flew out of the blood of Medusa when Perseus slew her, and being upside down when you gaze at Pegasus turning south. |
