  • AS11-37-5448 shows Schmidt during the early post-sunrise hours. The bright unrecognizable dot near the crater's southern rim ("left" of the crater) is Apollo 11's distant CSM Columbia. - DannyCaes DannyCaes Nov 18, 2007
  • An extreme king-size version of AS11-37-5448 in Kipp Teague's extraordinary Project Apollo Archive, shows the true appearance of the distant manmade CSM Columbia and the roughness of the moon's cratered surface in the background. Note the pitch-black shadow on Schmidt's floor. A superb photograph!!! - DannyCaes DannyCaes Dec 1, 2007

Additional Information


  • The present IAU name honors three men:
    • Johann Friedrich Julius Schmidt (October 25, 1825– February 7, 1884) was a German astronomer, and one of the foremost lunar observers of his day. By 1874 he put the finishing touches to his map of the Moon. This was the first map of the Moon to surpass the celebrated map of Beer and Mädler. See extended biography.
    • Bernhard Voldemar Schmidt (March 30, 1879–December 1, 1935) was an Estonian-born optician who lived in Germany. In 1931 he invented the Schmidt telescope which corrected for spherical aberration by placing a corrector lens in front of the mirror. His many accomplishments as a practical optician and telescope builder are all the more remarkable considering that he had lost most of his right arm in a childhood accident.
    • Otto Yulievich Schmidt (30 September 1891 — September 7, 1956) was a Soviet scientist, mathematician, astronomer and geophysicist. In mid 1940s, Schmidt suggested a new cosmogonical hypothesis on the formation of the Earth and other planets of the Solar system.

  • According to Whitaker (p. 221), the name Schmidt (presumably honoring J.F.J Schmidt) was introduced by Birt and Lee.
  • The name (honoring J.F.J Schmidt) was part of the original IAU nomenclature of Blagg and Müller (1935).
  • The other two Schmidt's were added as part of the list approved by the IAU in 1970 and published in Menzel, 1971.
