Reflector Telescopes

Invented by Sir Isaac Newton in 1668, the Father of the theory of gravity and celestial mechanics, it consists of a concave (shaped inwards) primary mirror of spherical or parabolic figure that reflects the light magnifying, enlarging or “Zooming in” the image like those magnifying mirrors that women use for face cleansing and make up. The light rays reflected from the primary mirror converge at a focal plane projecting an image through the reflection of another flat secondary mirror placed in the path of light being held by 3 or 4 spider vanes structure. This secondary mirror directs the light at a 90 ° angle towards the focusing tube where an eyepiece for observation or camera for astrophotography is attached.
