Before this post I have already shared some nice astronomy related software & stellarium is one of the best free planetarium software . It shows a realistic sky in 3D, just like what you see with the naked eye, binoculars or a telescope.

According to me stellarium is must try software even you don’t have interest in astronomy . It will create interest in you about astronomy . Working with stellaruim is so easy even you can zoom any star like you can do in telescope. The software has nice options to customize your observation even you can select what you have to see .






yeah.nice.
