Almost all constellations in autumn don't include so many bright stars, and perhaps you'll feel the autumnal sky empty.
But in the southern sky in autumn, you can find a lonely white star with the first magnitude of Fomalhaut at the mouth of the Southern Fish.
Pisces Austrinus is a fish lying on its back, and drinking water pouring from the jar of Aquarius.|
The origin of this constellation is uncertain, but was known in ancient times and is said to be the original "Pisces".
