The Galilee telescope
The telescope consists of two lenses: the objective lens and the eyeglass.
The two lenses are convergent, and the image of the star will be reversed.
The telescope of Galilee is shorter than the telescope, and it is distinguished by the eyeglass. The image of the star will be straight.
He built it because he was surprised at the phenomena he saw and he studied them. It serves as a telescope.
