Astro Lab 4 with Solar System View!

[Marcel]

Hi Salvomic!
Thank you for your reply. My last fonction was simple to program but hard to do in the Geometry apps. You must use the key and not the screen to use it because the objects are not lock, so they move if you want to move the screen. After some times, I find more simple to use only the key + and -.

If you have Mathematica or Wolfram Alpha, check for

"Solar system configuration now"

you will have what Astro Lab display!
