Hi Paul.
Do you have any particular interests in mind right now? If you let us know we may be able to give you more help and guidance.
I’ve been a variable star guy since the age of 14 when I started estimating the magnitude of delta Cephei with a mark-1 eyeball and managed to get a satisfactory light curve by folding on the known period before I took O Levels. (Incidentally, that shows roughly how old I am.) That made the VSS (Variable Star Section) a natural home for me.
Cheers,
Paul (another one)
