Thanks Malcolm.

It's a very gradual process for me, and I'm trying to learn new terminology and think about what I'm seeing, and trying to visualise, in a different way...so please forgive me if I'm paraphrasing like mad here..

So am I right to think in RA we have hours, minutes and seconds, up to 23 hours, 59 minutes, 59 Seconds, and these do relate to time? Is Greenwich 0hr 0' 0"?

In DEC, is it between +90º (N) and -90º (S)? And each degree is also divided into arc minutes and arc seconds, but in this case they have nothing to do with time, but are just subdivisions of a degree of angle?

Thanks for all your replies, I really appreciate the help
