spectroheliograph

In 1932, Robert extended the functionality of the spectroheliograph so that it could record motion pictures of the sun.

Deslandres developed the spectroheliograph simultaneously with George Hale.

The spectroheliograph is an instrument used in astronomy which captures a photographic image of the Sun at a single wavelength of light, a monochromatic image.

Kenwood's principal instrument was a twelve-inch refractor, which was used in conjunction with a Rowland grating as part of the spectroheliograph.

The converging solar beam from the objective can be diverted to a high dispersion spectroheliograph with Littrow arrangement using a 3.43 m achromat.

The two prism K-alpha spectroheliographs were acquired in 1904 and the H-alpha Diffraction grating spectroheliograph was operational in 1911.

The spectroheliograph, an instrument that shows the distribution of the elements in the sun's atmosphere, was invented by George Ellery Hale (18681938), the observatory's founder and first director.

The spectroheliograph was invented in 1893 by George Ellery Hale and independently later by Henri Alexandre Deslandres in 1894.

The American solar astronomer George Ellery Hale, as an undergraduate at MIT, invented the spectroheliograph, with which he made the discovery of solar vortices.

By 1961 the radio-interferometer calibration techniques developed for the spectroheliograph first allowed an antenna system, with 52" fan beam, to equal the angular resolution of the human eye in one observation.

Maybe we can start with the spectroheliograph deployment procedure..." When she flew once more over the glittering east coast of North America, the Gaijin ship was waiting to meet her.

In 1908, Hale used a modified spectroheliograph to show that the spectra of hydrogen exhibited the Zeeman effect whenever the area of view passed over a sunspot on the solar disc.

Dr. Robert R. McMath of the McMath-Hulbert Observatory used a spectroheliograph to make time-lapse films of the prominences on the Sun.

At Stanford Professor Bracewell constructed a microwave spectroheliograph (1961), a large and complex radio telescope which produced daily temperature maps of the sun reliably for eleven years, the duration of a solar cycle.

It was here that the spectroheliograph, which Hale had invented while attending MIT, was first put to practical use; and it was here that Hale established the Astrophysical Journal.

Partway through the millennium, we figured out how to shape and polish glass so as to see far and to see small, and we dug back into dead languages of previous millenniums to name our new aids to seeing - telescope, microscope, spectroscope, spectrophotometer, spectroheliograph and, eventually, television.
