Who invented telescope in India?

By figuring out an optimum distance at which to place the lenses and mounting them in a tube, Lippershey invented the telescope. He liked what he saw with it, and applied for a patent. He also conducted a demonstration with his prototype – the first optical refracting telescope – on October 2, 1608.
