Constellation of Pisces is an autumnal zodiac positioned at next to Aquarius.
The constellation is depicted as two fishes connected their tails at alpha Picium, "Alrescha" meaning of a knot.
It's rather faint, and is hard to follow the series of dimmed stars. The sun crosses the celestial equator just around the tail of the western fish; in fact the vernal equinox is included in Pisces now. The vernal equinox is established as the right ascension of zero, and Pisces must be the first zodiac. But in the times of ancient Babylonia, the vernal equinox was lied in east neighbored Aries, so Pisces is registered as the last zodiac in the astrology even now. This image has been cropped with an equivalent focal length of 24mm. |
