Cassiopeia is one of the most recognizable constellations in the skies because of its distinct "W" shape.
Cassiopeia is surrounded by family, her husband, Cepheus, lies to the north-east of her.
Cassiopeia, on the other hand, felt that Andromeda would be better off with her former suitor, Agenor.

Cassiopeia is a northern constellation which Greek mythology considered to represent a vain queen.
Cassiopeia was the site of Tycho Brahe's supernova of 1572 (SN 1572), and is also the location of Cassiopeia A, the strongest radio source in the sky (other than the sun).
Cassiopeia A is the Supernova remnantremnant of a supernova which apparently occurred in about 1667, although there is no record of it having been observed.

 Eta Cassiopeiae 2
Also called Achird, Eta Cassiopeiae is located about 19.4 light-years (ly) from our Sun, Sol, in the central part (00:49:06.29+57:48:54.67, ICRS 2000.0) of Constellation Cassiopeia, the Lady of the Chair -- northeast of Schedar (Alpha Cassiopeiae) and southwest of Mu Cassiopeiae.
The distance from Eta Cassiopeiae A where an Earth-type planet would be "comfortable" with liquid water is centered around 1.13 AU -- just a little farther than Earth's orbital distance in the Solar System.
Cassiopeia's vanity so angered the sea god Poseidon that he had Andromeda chained to a rock of the coast as a sacrifice for Cetus (the monstrous whale) until Perseus rescued her.

 Messier Guide: Early Autumn
What is particularly puzzling about this is that Cassiopeia is crammed with magnificent open clusters; in fact, there are half a dozen clusters within two degrees of M103, of which at least one (NGC 663) is far more prominent and attractive than M103, especially in small instruments and under poor skies.
They are also quite easy to locate, as Cassiopeia is one of the most compact and recognizable of all the constellations.
Remember that the W side is the one containing the star Eta, which at mag 3.5 is nearly as bright as the five stars that outline the constellation's basic shape.

Cassiopeia, the wife of King Cepheus, ruler of Ethiopia, was beautiful, arrogant and vain, and it was these latter two characteristics which were to lead to her downfall.
Her continual boast that both she and her daughter Andromeda were more beautiful than the sea nymphs, daughters of Nereus, the sea god, brought the wrath of Poseidon, ruling god of the sea, upon the kingdom of Ethiopia.
Poseidon considered that Cassiopeia should not escape punishment entirely, and placed her in the heavens in such a position that she circles the celestial pole in an upside-down position for half the time.

Cassiopeia is located about 30 degrees above the north-northwestern horizon about 9 p.m.
Sky watchers should scan about 6.5 degrees to the upper right of Epsilon in order to spot Machholz, which is still relatively bright at 4.9 magnitude.

Epsilon Eridani is 10ly from Earth, and assuming he double his travel time as a result of the Cole Protocol [we know he didn't completely obey the protocol, which would probably have quadrupled his time], he would be travelling 10ly every 60 hours, or 4ly per day.
It is mentioned that the Ascendant Justice / Gettysburg travelled a distance that would normally require a few days, after fleeing from Epsilon Eridani.
If we assume a distance of 10ly from Reach, then the most likely single-star candidate [I don't recall Eridanus being binary] is 82 Eridani, which is conveniently in the constellation of Eridanus.
