Spigl, who was from a surveying background, progressed rebuilding a post war ravaged Observatory by rejuvenating the time service, seismology services, completing the Astrographic Catalogues, became involved in the International Geophysical Year by installing a Markowitz Moon camera and restarted the publications for the Royal Astronomical Society.

The U . S . Naval Observatory ( USNO ) first compiled the ACT ( Astrographic Catalog / Tycho ) Reference Catalog, containing nearly one million stars, by combining the Astrographic Catalogue ( AC 2000 ) with the Tycho-1 Catalogue; the large epoch span between the two catalogues improved the accuracy of proper motions by about an order of magnitude.

"' Joseph Rheden "'( April 5, 1873 August 6, 1946 ) was an Austrian astronomer, born in Amlach, East Tyrol, known for his astrographic observations of planets, minor planets and comets, and for the asteroids 744 Aguntina, 771 Libera, and 844 Leontina, which he discovered in 1913 and 1916, respectively.

The greatest known aggregation of these co-located " Junctions " or Terminus Loci occur in the Manticore binary star system, whose wormholes connect the wormhole junction to six ( later seven ) other star systems, giving the Manticore system an astrographic position to be coveted, and an immense revenue stream from transit tolls, manufacturing and trade, and a large carrying trade.

The "'Carte du Ciel "'( literally,'Map of the Sky') and the "'Astrographic Catalogue "'( or "'Astrographic Chart "') were two distinct but connected components of a massive international astronomical project, initiated in the late 19th century, to catalogue and map the positions of millions of stars as faint as 11th or 12th magnitude.

For the first, the Astrographic Catalogue, the entire sky was to be photographed to 11 mag to provide a reference catalogue of star positions that would fill the magnitude gap between those previously observed by transit and meridian circle instrument observations down to 8 mag & ndash; this would provide the positions of a reasonably dense network of star positions which could in turn be used as a reference system for the fainter survey component ( the Carte du Ciel ).
