===================

Saturn as recorded by our planetary telescope with a high speed camera to reduce
blurring by Earth's atmosphere.  The color images are approximately true color
made by taking separate images in red, green and blue filters and combining them
to make a color composite.  Details are below.

The images include exposures to show the satellites, an image with satellites
labeled, and a map of the location of the satellites at the time of the
exposures.
