Celestial Coordinates question

[Shandy]

Hi all, can anyone tell me - where the celestial equivalent of the Grenwich Meridian lies? IE: RA 0

Thanks

Hi Shandy,

It runs from Polaris, past the end of Cassiopeia and through Pegasus, just missing the star Alpheratz. On through Pisces just missing Omega Piscium, across the ecliptic, past the nose of Cetus and on through Sculptor.

Any of the free planetarium software programs, like Cartes du Ciel or Stellarium, can show you.

Thanks - which end of cassiopea?

The Caph (β Cassiopeiae) end.
