A telescope which uses mirrors to gather and focus light.
A type of telescope that uses a mirror or mirrors to form the primary image.
A telescope that uses a mirrored, concave, surface to bring the image to a focal plane. The most common type is known as a "Newtonian" reflector - named after Sir Isaac himself. These are popular with amateurs due to their low cost, ease of construction, and good images.
A telescope that has a concave mirror which collects and focuses the light from a celestial object. The majority of modern telescopes are reflectors because they are inexpensive and compact.
Telescope that uses mirrors to collect and focus incoming light.
A telescope that uses a mirror to focus light.
A telescope which uses a mirror to gather and focus light from a distant object.
A telescope where mirrors are the optical elements, not lenses.
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"
an optical telescope using mirrors to gather and reflect the light
a telescope that catches light on a large concave primary mirror
A type of telescope that focuses light with a curved mirror
A telescope in which the principal optical component (objective) is a concave mirror.
A telescope that uses mirrors to collect and focus light.
An optical system where light is bent with a curve mirror.
telescope using a concave parabolic mirror to increase focal length and focus light at a point.
A reflecting (or Newtonian) telescope uses two mirrors which magnify what is viewed. The first reflecting telescope was first described by James Gregory in 1663.
A reflecting telescope (reflector) is an optical telescope which uses a combination of curved and plane (flat) mirrors to reflect light and form an image (catoptric), rather than lenses to refract or bend light to form an image (dioptric).
