It’s another good open source program for viewing celestial maps. Compared with Stellarium, it is perhaps more suitable for older computers, and more plugins, scaribili separately from the site (the graphics are good, but not equal to Stellarium). Here again, clicking on the various stars of the sky can be obtained on the same information (magnitude, spectral type, etc.)..
It’s a great open source program that can show us the sky, with information on about 120000 stars (including constellations, planets, etc.).. View the sky in a realistic 3D perspective, simulating the visual to the naked eye, binoculars or telescope. And can see the sky is the atmosphere that without (the visual atmosphere is nice, but if you want to see the stars you’ll have to turn it off), and have information about distant stars (magnitude, distance, category, spectral) simply clicking on them. The zoom allows you to go and see the selected celestial body as if you were using a telescope.
Very, very nice.
