Instr.: A telescope constructed by Sir William Herschel, in 1789, or any one of a similar type. The mirror was so inclined that the image of a star was formed on the side of the telescope near the eye-piece, hence it was sometimes called the front-view telescope. The rays undergo only a single reflection, and there is therefore but little lo of light. The magnifying power is the quotient when the powerful focal distance of the mirror is divided by the focal distance of the eye-piece. The instrument constructed by Herschel was forty feet long, with a mirror of fifty inches diameter. It was the most magnificent telescope which had ever been made, and was not exceeded till that of Earl Ro e was constructed. [TELESCOPE.] Her-schel-ite, s.
