Hi Adam,

A very belated answer to this one: Guide doesn't show the
earth shadow. Something I probably ought to add at some point.
It would be well if the height of the shadow were adjustable,
so you could ask Guide to show "the shadow out where the moon
is" vs. "the shadow out where a particular artificial satellite
is." It's a feature that is requested every now and then. Of
course, both the outline of the umbra and the penumbra should
be visible.
