The name ‘Newtonian’ is given to the configuration with two mirrors used by Newton. Why are reflecting telescopes more commonly used in science? Because they are easier to mount as the size of the telescope grows, and they have fewer defects (aberrations) than refracting ... WebIf inventing means being first to publish an effective design for a reflecting telescope then the inventor is Marin Mersenne (1636) or Bonaventura Cavalieri (1632). If inventing means the first to design and build a minimally functional reflecting telescope then the inventor is Isaac Newton (1668). History is not always cut and dried. fitness gear power band
