Hydra together with the ecliptic cycle forms a
figure like Q. We
have investigated the stars both in Leo and
Hydra.
Our last star in Leo is
υ (176.2) and our
last star in Hydra is π (214.0). With Hydra
taking off to the south we should expect to find a similar behaviour
of some constellation at the other side of the equator. Half the sky
away we have Andromeda, at the beginning of
right ascension time, and with her left elbow
she is reaching down towards Pisces:

far only the following Greek lettered stars in

17 = 24. NGC 752 is an open cluster of stars and of no
interest for us.
But
the planetary nebula NGC 7662, the Snowball Nebula, is
beautiful:
