From John Karl's "Celestial Navigation in the GPS Age":
"...the whole-horizon mirror makes high-contrast sights (such as the sun and stars against a dark sky) more convenient, but it makes low-contrast sights (such as dim stars against a twilight sky) more difficult - sometimes impossible. ...the whole-horizon mirror makes easy sights easier, and hard sights harder."
