Presentation Transcript

  1. Rise of the Telescope: Galileo

  2. Rise of the Telescope: Galileo Photographs taken using a telescope similar to Galileo’s by Tom Pope (www.pacifier.com/~tpope) compared to engraving from Sidereus Nuncius. Upper photo corresponds to a Keplerian telescope; lower is what Galileo would have seen. January 19, 1610 stellar occultation

  3. Rise of the Telescope: Galileo Copernicus, Heraclides or Tycho Galileo’s drawing of the phases of Venus and modern photo-mosaic Ptolemy

  4. Rise of the Telescope: Galileo The discovery page from Galileo’s notebook A later systematic study One of Tom Pope’s photographs

  5. Rise of the Telescope: 17th cen. Hevelius, 1643 Hevelius, 1647 Riccioli, 1651 Huygens, 1659

  6. Rise of the Telescope: 17th cen. Scheiner’s helioscope, 1638: first equatorial mount Roemer’s transit circle, 1684

  7. Rise of the Telescope: 17th cen. Hevelius’ 60-foot telescope, 1673 Huygens’ aerial telescope, 1684

  8. Rise of the Telescope: Newton Newton’s reflector, 1671 Newton’s drawing of his prism experiment. This demonstrates the cause of chromatic aberration (and the basis of spectroscopy) Second prism shows no further change

  9. Rise of the Telescope: Hadley Gregorian reflector with 6-in mirror, 1721. Also invented sextant, 1730.

  10. Rise of the Telescope: Herschel

  11. Rise of the Telescope: Lord Rosse

  12. Rise of the Telescope: Dollond Image of slit through 20 cm single lens and doublet, http://www.physics.umd.edu/lecdem/

  13. Rise of the Telescope: Parallax Dorpat refractor Konigsberger heliometer Fraunhofer Struve Henderson Bessel

  14. Rise of the Telescope: the AU 1769 Venus transit First radar measurement

  15. Photography Chromatic aberration in an achromatic refractor set up for visual use Lewis Morris Rutherfurd

  16. Photography Henry Draper’s 1882 photo of the Orion Nebula A modern HST image

  17. Photography John Herschel, 1830s Lord Rosse, 1840s Henry Draper, 1882 David Malin, 1979 Small images from http://www.rit.edu/~photo/IFS/About-IFS.html

  18. Photography Early photographs from Pedro Re’s collection of scanned plates: above M31 and M33 by Isaac Roberts; above right Comet Swift in 1892 by EE Barnard; right the Pleiades by JE Keeler

  19. Spectroscopy Fraunhofer’s 1823 spectrum compared with a modern spectrum of similar dispersion. Early photographic spectrum by William Huggins showing nebular lines

  20. Spectroscopy Harvard College Observatory spectro-scopy for the Henry Draper catalogue
