The stellarium is a free festival plank of 3D, available for three main operating systems, where you can monitor the sky at night, as you are looking through a telescope.
You control the program using your mouse or toolbar. You will see the planets, nebulas, constellations, and their location and name that appear in your sky.
You can set to display a specific time of day and even imitating eclipses. Your screen capturing and video recordings for your friends and family will also be for your intermittent journey.
All this makes Stellarium a very playful astronomical app.
