Tip: You can also turn on light pollution
by right-clicking (Ctrl-click on the Mac)
on the background sky in the main window.
This will open a contextual menu with two
light pollution options: Local Light
Pollution and Distant Light Pollution.
Tip (Pro and Pro Plus only): Another way
to customize light pollution levels is to
specify a limiting magnitude for celestial
objects, especially stars. See “Constrain
”
on page 40 for more information.

Ambient environment sounds can be
played in the background by checking the

down menu lets you choose from one of
