Originally from ticket #4780.
Now I have a few simple questions:
1. If I adjust my horizon to be straight - horizontal, the sky is only about
2/3 of my screen height (horizon is about at 1/3 from the bottom). How can I
move the horizon completely down (and still be straight i.e. not bent) in
order to have the full height of screen available for the sky?
2. Sometimes the horizon suddenly gets “round” and looks like a circle,
which is not practical at all. After some further operation it suddenly gets
straight and horizontal again. How can I avoid that this happens, and what’s
wrong with my manipulation?
3. Can I show the mutual movements of selected planets over a period of time
and simultaneously stop the daily movement of the sky? For instance fix
Venus on the screen and watch Mercury move relative to Venus over a month or
a year (i.e. Venus stays centred on screen)?
4. I have tried to look at the solar system from high above the sun. I can
see the planets (as dots) moving around the sun. But can I stop the sky
moving, while the planets keep moving (similar to point 3 above)? Can I see
the planets in different colours? Can I see the orbits (instead of planets
as dots) and in colours? Etc.
5. If I choose “Planets” I wish to see planets only and no "Minor Planets"
like Ceres. Possible?
Thank you for taking your ime for my questions!
