reflecting telescope, reflector

optical telescope consisting of a large concave mirror that produces an image that is magnified by the eyepiece; "Isaac Newton invented the reflecting telescope in 1668"

• Cassegrainian telescope, Gregorian telescope — a reflecting telescope that has a paraboloidal primary mirror and a hyperboloidal secondary mirror; light is brought to a focus through an aperture in the center of the primary mirror
• coude telescope, coude system — a reflecting telescope so constructed that the light is led to a plate holder or spectrograph
• Herschelian telescope, off-axis reflector — a reflecting telescope with the mirror slightly tilted to throw the image to the side where it can be viewed
• Maksutov telescope — reflecting telescope in which the aberration of the concave mirror is reduced by a meniscus lens
• Newtonian telescope, Newtonian reflector — reflecting telescope in which the image is viewed through an eyepiece perpendicular to main axis
• Schmidt telescope, Schmidt camera — reflecting telescope that has plate that corrects for aberration so a wide area of sky can be photographed

• optical telescope — an astronomical telescope designed to collect and record light from cosmic sources

• parabolic mirror — a parabolic reflector for light radiation
