Yes - this is what I am looking for. An app with map overlays would be more
useful. Let's say I wanted to take a picture of the moon rising over 4
Peaks. Where would I need to setup beforehand to take the picture?
Jim,
In Google Earth, hold down the shift key while you pan downward, and the view
will become more oblique. In the middle of the buttons across the top is on
that shows the sun over mountains (Show sunlight across the landscape). Click
that button, and a time slider appears that you can run forward or backward.
You'll notice that it shows the correct position of the constellations in the
sky at night, and the brightest stars during the day. You can also zoom in and
out on the time slider to expand the range of dates.
The only problem is that Google Earth shows everything in the sky except the
moon! You would need to use a separate app to tell you where the moon is
against the stars, and then go from there.
The way I've gone after this problem in the past is to let SkySafari give the
azimuth of the rising object, and then have Google Earth tell me where to go to
get the object to rise over the desired Earth feature.
