Japan 1953 – Tokyo Observatory
The 75th anniversary of the founding of
Tokyo Observatory was marked by the release of this stamp.
Cassiopeia, Polaris and the Plough form a backdrop to the open
dome of the observatory’s main telescope, a twin-tube
equatorial refractor with objective lenses of 0.65-m and 0.38-m
aperture which was built in 1926 and is the largest refractor
in Japan. The observatory was originally based at the
University of Tokyo but moved in 1924 to Mitaka city, 20 km
west of Tokyo. Since 1988 it has been the headquarters of the
National Observatory of Japan and larger instruments have been
established on better sites elsewhere, most notably the Subaru
telescope on Hawaii. The old telescopes such as the twin
refractor are kept at Mitaka for historical purposes and public
display.
