Orion variable polarizing filter, set to almost opaque, used
to drastically cut down on the moon's brightness. First ten subs
framed to create a "left" image, second ten to create
a "right" image, last ten to create a "top"
image. Each set of ten averaged after registration of subs in
Registar, which was also used to register the three mosaic frames.
