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?
