From C&P’s site:

“Polarizing Shade
Glasses
One each set of polarizing shades are for
the star and horizon view. This allows simple brightness control of star and
horizon image. Dazzling will be avoided. Sudden changes of brightness caused by
movement of clouds will simply and quickly be corrected. ”
It sounds as though a set of polarizing filters comes as
standard with the Horizon Ultra. There would have to be two for the brightness
control promised, by selectively turning either or both.
