 The self leveling
 nature of liuid AH will always beat a mirror for accuracy.
 Calibrating the level(s) and other things affect true
 leveling of a mirror. But the mirrors really shine with
 their ability to reflect even dim starlight. Why limit
 yourself to the sun, moon and perhaps Venus, when a mirror
 opens up the entire sky? You can get better cuts of LIPs and
 more sight options when clouds block parts of the sky.
