Refracting: A refracting telescope employs two lenses to collect, focus and magnify more light than is otherwise possible with just the naked eye.
Catadioptric:Catadioptric telescopes are optical telescopes that combine specifically shaped mirrors and lenses to form an image.
Dobsonian:Dobsonian telescopes are known for their large aperture and low magnification.
Solar:Solar telescopes may employ a variety of technologies, from simply projecting the sun onto white paper, using a hydrogen-alpha filter, or a spectrohelioscope.
Optical Tubes:Optical tubes is the main body of the telescope.
Binocular: A Binocular telescope has two eye pieces for the object can be viewed by both eyes.
