Hi Brett,

to IIS.
Yes, I know what you mean about the constellations. They seem to be different in every star chart or atlas. I presume that over the centuries they have been interpreted and drawn up by different people and just visualised a bit differently. I think you'll find though that each different interpretation includes all the same stars, just joined up a little differently.
I just try to learn the stars belonging to each constellation and not worry about wether they are joined the same way.
Someone else might know a little more about this, hopefully they'll pipe in.
Ask any questions you like, no matter how dumb you think the question is, there's lots of friendly and knowledgable people (I'm not one of the knowledgable ones

) around here.
