Description
Astronomical instruments used by Norman Lockyer at the Science Schools, South Kensington, England to obtain the spectra of nebulae, including the Great Nebula in Orion. The image shows a 10-inch object glass on an adjustable tripod stand, with a collimator directed at a siderostat. The visible wires at the tripod lead to a hut (not visible) containing the spectroscope.
Plate from the manuscript version of the paper ‘On the chief line in the spectrum of the nebulae’, by J. Norman Lockyer, Proceedings of the Royal Society, vol.48 (1890), pp.167-198. The illustration appeared in the published paper as figure 2, a line engraving, without the central buildings.
The print has pencilled marks over the image to indicate to the printer the areas to remove in the printed version. Inscribed in pencil verso: ‘Fig. 2. This may be reduced and background omitted if necessary’.
Sir Joseph Norman Lockyer (1836-1920) British astronomer, was elected a Fellow of the Royal Society in 1869.
