1851- First daguerreotype of a total eclipse of the Sun obtained by M. Berkowski , recording the inner
corona and several prominences (July, 28) (Figure 4). In Rome Angelo Secchi (1818-1878) records the
partial phases of the eclipse (daguerreotypes) (162 mm refractor, 2.5 m focal length).
1852- First wet plate collodion images of the Moon obtained by Warren de la Rue (1815-1889) using a 33
cm reflector with 3.05 m focal length. Mount without a clock drive.
1853- J. Phillips photographs the Moon with a 159 mm refractor (3.35 m focal length) (60 s exposures).
1854- Joseph Bancroft Reade (1801-1870) uses a 60 cm reflector to photograph the sun (wet collodium).
These images reveal the solar molted appearance (photosphere).
1855- Warren de la Rue publishes A series of twelve photographs of the Moon.
1856/1858- Lewis Morris Rutherfurd (1816-1892) photographs the Moon and the Sun using an
achromatic refractor of 285 mm aperture.
1857- George Philips Bond (1825-1865) (son of W.C. Bond) photographs (wet collodion) the double star
Mizar (ζ UMa) and Alcor (80 UMa) using the 38 cm Harvard refractor (Figure 5).
1857- Warren de la Rue obtains images of Jupiter and Saturn with a 33 cm reflector. The exposures (12 s
for Jupiter and 60 s for Saturn) were unsuccessful (the planet images measured only 1/2 mm on the
plate).
1858- Warren de la Rue tries to image comet Donati without success. M. Usherwood records the comet
with a 7 s exposure.
1858- George Philips Bond shows that the magnitude of stars could be derived from astronomical
photographs (stellar photometry).
1958/1859- Warren de la Rue publishes the first stereographs of the Moon (by obtaining images at
different librations) (Figure 6).
1858/1872- Warren de la Rue obtains daily images of the Sun (weather permitting) using the Kew
photoheliograph (Figure 7). A total of 2778 Sun photographs were obtained between 1862 and 1872.
1860- Warren de la Rue photographs (wet collodion) the total eclipse of the Sun in Spain (July, 18) with
the Kew photoheliograph (60 s exposures) (Figure 7). Angelo Secchi also obtains excellent photographs of
the same eclipse (Spain).
1861- Warren de la Rue mentions the possibility of conducting a photographic survey to obtain a Star
Map of the whole sky (astrometry).
1861- James Clerk Maxwell (1831-1879) demonstrates a color photography system involving three black
and white photographs, each taken through a red, green and blue filter.
1865- Lewis Morris Rutherfurd obtains excellent Moon images using a specially corrected (photographic)
290 mm lens (Figure 8).
1864/1865- Henry Draper (1837-1882) images the Moon using a 40 cm reflector built by himself.
1871- German astronomer Hermann Carl Vogel (1841-1907) obtains excellent photographs of the Sun
using a 294 mm refractor equipped with an electrical shutter (1/5000 to 1/8000s exposures).
1871- Richard Leach Maddox (1816-1902), proposes the use of an emulsion of gelatin and silver bromide
on a glass plate, the "dry plate" process.
1871- Lord (James Ludovic) Lindsay (1847–1913) photographs the total eclipse of the Sun (December,
12) at Baikul (Figure 9).
1871- Lewis Morris Rutherfurd records the solar molted appearance with some detail.
1872- Henry Draper records the spectrum of α Lyra using a 720 mm reflector.
