Spectroheliograph
From LoveToKnow 1911
SPECTROHELIOGRAPH, an instrument for photographing the sun with monochromatic light.
Spectroheliograph
The spectroheliograph is an instrument used in astronomy. It captures a photographic image of the Sun at a single wavelength of light, a monochromatic image.

George Ellery Hale invented the spectroheliograph, which can be used to take pictures of the Sun in any wavelength. After using the instrument on the great Yerkes refractor in Williams Bay, Wis., U.S.
Then came the accessories--spectrometers to split the light and deduce from its spectrum the composition of stars, and spectroheliographs to observe the Sun in just one color--the source being so bright that an astronomer could get a good image ...

The spectroheliograph was invented in 1890 independently by G. Hale and by H. Deslandres and modernized (1932) by R. R. McMath to take motion pictures.
Hale invented the spectroheliograph (a device used to analyse the Sun's spectrum) when he was an undergraduate at the Massachusetts Institute of Technology (Cambridge, Massachusetts, USA).
The first astrophysicist, invented the spectroheliograph allowing photography of solar prominences in daylight, discovered magnetic fields in sunspots, planned and completed the 200-inch Mt. Palomar telescope.

the amount of light in each range of wavelength, that is, in each range of color. In general, each type of astronomical object, such as a star or a galaxy, will emit a characteristic spectrum of light. (see Spectrum.) [LB90]

Prominences can be observed visually (optically) whenever the sun's disk is masked, as during an eclipse or by using a coronagraph; and can be observed instrumentally by filtering in certain wavelengths, as with a spectroheliograph.
