Where the twelve signs came from, and why they carry the names they do.

Why Mizar matters
Mizar connects a traditional eyesight test with the modern discovery that apparently simple stars can contain multiple nested systems.
How to read Mizar
Find the middle of the Dipper handle and look for faint Alcor beside Mizar before applying telescope magnification.
Mizar in practice: an example
A telescope splits Mizar A and B, while spectroscopy reveals each as a closer pair.
Where readings of Mizar go wrong
Mizar and Alcor are more than an optical coincidence, but the full system architecture is more complex than one double.
