    I am sorry to somewhat, in a sense, repeat myself.

    But same as you I wanted to get my head around the celestial coordinates systems. As used both in astronomy and celestial navigation. Investigated it, and this is the result:

    Star locations?
    From: Samuel L

    I've having a hard time in figuring out or understanding the Star SHA figure and what it means.

    For example- Arcturus is 145d 55.2 min. with a declination of 19 d 6.6 min North.

    What in the world does that mean? I assume it someway corresponds to RA and Dec (RA, of course is meaningless...to say it references off of Aries or the Spring equinox is even MORE meaningless as I would understand it better if were referenced off some real place like Greenwich).

    Can someone please explain that stuff?

    Thank you,

    Sam Lohengrin
