Schmidt
subject			fact

Schmidt	has secondary mirror shape none
	has primary mirror shape concave spheroid
	has optical design Schmidt
	has definition Telescopic camera incorporating an internal corrective lens or plate that compensates for optical defects and chromatic faults in the main mirror. The system was invented by Bernhard Schmidt.
	has definition A telescope with a spherical primary mirror and a thin refractive corrector plate with a complex, non-spherical shape. Very wide-field performance for surveys.
	has definition A type of reflecting telescope (more accurately, a large camera) in which the coma produced by a spherical concave mirror is compensated for by a thin correcting lens placed at the opening of the telescope tube. The Schmidt has a usable field of 0°.6.
	is a kind of reflector
	is a kind of equatorial telescope
equatorial telescope	has mounting equatorial
reflector	has mirror maker the person, company or institution that created the mirror
	has mirror type material and other engineering details
	has mirror diameter equal to aperture (except for Schmidt which has aperture smaller than mirror diameter)
	has aperture or primary mirror diameter
Earth based telescope	has mounting manufacturer the person, company or institution that constructed the mounting
	has longitude in degrees, minutes, seconds (E or W)
	has latitude in degrees, minutes, seconds (N or S)
	has altitude height above sea level in meters
	has temperature ambient
telescope	has wavelength sensitivity
	has angular resolving power
	has effective diameter
	has focal ratio
	has operator
	has purpose observe celestial objects

physical object	has angular momentum
	has mass
	has velocity
	has momentum
	has volume
	has extent
	has material
