Helioscope

   Also found in: Dictionary/thesaurus, Wikipedia 0.01 sec.
helioscope [′hē·lē·ə‚skōp]
(optics)
A telescope for observing the sun that protects the observer's eyes from the sun's glare.
Helioscope 

an astronomical telescope adapted for visual observations of the surface of the sun. Dark filters, silvered objectives, and special helioscopic eyepieces are used to diminish the brightness of the solar disk, making it possible to decrease the amount of light striking the eye. At the present time helioscopes play a secondary role since research on the sun is done largely by photographic methods.

Siebert's most striking contribution in this remarkable volume is his painstaking reconstruction of Kircher's cosmological system, with its careful effort to preserve the essence of Church doctrine by retaining a fixed center point for the great cosmic machinery, and yet taking into account the evidence provided by decades of research with telescope, helioscope, and more traditional astronomical instruments.
