Hi guys!
Straight into it!
Celestial sphere = imaginary rotating sphere (got it)
Meridian = ???? no idea
celestial poles = point on the celestial sphere above arctic ocean (North) and antarctica (South)??
The reason for this is I'm going to attempt polar aligning my scope for tracking!

I've been trying to read up on it, but some sites have me confused. Why do they have to use big words like 'meridian' and 'celestial polse'..? Why can't they just say, "point your scope at this star!!" Done!
