Constellation shapes?
I was looking at my large Chandler planisphere last night and noticed that the lines drawn to make up the constellations are not the same as other sources I've seen. For instance, if I use my book "A walk through the southern sky", Centarus is quite markedly different - not just in the way the same stars are joined together, but they even use some differemnt stars.
This got me thinking : Has the Chandler just approximated constellation lines due to size constraints? Or are the shapes and make-ups of constellations not an exact science? Is there room for different opinions from source to source?
I had just made the assumtion that they were set in stone. Perhaps I was wrong there.
