horizon, i wanna some like the way it's this picture) Another words I
wanna shrink horizon.

Hi,

You can use the up and down arrow keys on the keyboard to change the
horizon's position. Once you get it the way you want it, exit kstars and
it will remember the new position the next time you open it.

If you go to View | Equatorial Coordinates you can get rid of the
horizontal coordinates altogether.

You can use the + and - keys on the keyboard to zoom in and out and
further adjust the size of your view and the horizon.

Pressing f1 will open up the Kstars manual. It has some more info on
customizing the view, positions, etc.

Good luck,

Josh
