In an astronomy app name SkyPortal you can see the constellation lines as Modern or Traditional lines.
The traditional ones rarely have a resemblance to what they are a symbol of. However, the modern lines make much more sense.
Is there any reference for modern constellation lines? Any online resource to show or discuss them?
I was under the impression that these lines are historical. Just after asking this question, I looked at the images on the Book of Fixed Stars and realized the original book doesn't have the lines at all. So these lines are something new.
