Johannes Kepler Telescope Invention. Johannes kepler first explained the theory and some of the practical advantages of a telescope constructed of two convex lenses in his catoptrics (1611). Working from kepler's writings, isaac newton reasoned it was better to make a telescope out of mirrors rather than lenses and built a reflecting telescope in 1668.

Found in the collection of the museo galileo, florence. The keplerian telescope, invented by johannes kepler in 1611, is an improvement on galileo's design.
Borucki.after nine and a half years of operation, the telescope's reaction control system fuel was depleted.
Johannes kepler created one type, known as a refracting telescope, in 1611. Working from kepler's writings, isaac newton reasoned it was better to make a telescope out of mirrors rather than lenses and built a reflecting telescope in 1668. Johannes kepler publishes the book his first scientific work known and appreciated is the book mysterium cosmographicum (cosmic mystery). It uses a convex lens as the eyepiece instead of galileo's concave one.
