[amsat-bb] instant track and eclipse

["Bruce Paige" <kk5do@xxxxxxxx>]

for those using instant track (any version), while viewing the tracking map, 
you can change to the sky view. to do this, type 4P (to get back to your 
normal view, type 1P).

in the sky view from the instant track manual, here is what you will see..

"The sky-view projection is a map of the sky from the perspective of an 
observer at your location looking toward the satellite. The satellite is shown 
on this map along with the 920 brightest stars, and possibly the Sun, the 
Moon, and the horizon, if they happen to be in view.

The map is a Gnomic projection (which is a fancy way of saying that it is a 
perspective projection of the celestial sphere from the viewpoint of a person 
at the center of the sphere), with the field-of-view that extends 100 degrees 
horizontally, and 60 degrees vertically. The sky-view is always roughly 
centered on the satellite."

nice feature....you can see the satellite and then the sun/horizon as it pertains 
to this eclipse period. pretty neat to watch...you can even hit F for fast forward 
and see when the next eclipse will be and how it will look.
