Below the SkyTools Visual Sky Simulation displays the shadows of three of Jupiter's moons cast onto the cloud tops of the planet. These simulation charts are also used for star hopping (usually printed in black on white for use at the telescope). SkyTools 3 uses a sophisticated model for sky brightness and visibility that includes light pollution, moonlight, twilight, extinction, seeing, and detection contrast. There are three views. Each can be individually enabled/disabled, moved about the window, and resized to fit your needs.
Naked Eye View -- provides the context of the finder view (inset square around Jupiter). The gets your oriented in the sky.
Finder View -- this is the key view for star hopping (of course in this case Jupiter is fairly obvious). This view helps you point the telescope at (or near) the target using your magnifying finder, Telrad, Quikfinder, etc.
Eyepiece View -- This is a simulation of Jupiter as seen in a 20-inch Obsession. The resolution on the screen matches the resolution you would expect to see in the telescope under current seeing conditions.
