cds-question@unistra.frastrometryThis article describes the assembly of an optical (RGB) all-sky mosaic image with an image scale of 36"/pix, a limiting magnitude of approximately 14mag, and an 18 bit dynamic range. Using a portable low-cost CCD camera system, 70 fields (each covering 40{deg}x27{deg}) were imaged over a time span of 22 months from dark-sky locations in South Africa, Texas, and Michigan. The fields were photometrically calibrated against standard catalog stars. Using sky background data from the Pioneer 10 and 11 space probes, gradients resulting from artificial light pollution, airglow, and zodiacal light were eliminated, while the large-scale galactic and extragalactic background resulting from unresolved sources was preserved. The 648 megapixel image is a valuable educational tool, being able to fully utilize the resolution and dynamic range of modern full-dome planetarium projection systems.2009PASP..121.1180Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/PASP/121/1180CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/PASP/121/1180https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/PASP/121/1180http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/PASP/121/1180https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/PASP/121/1180https://vizier.iucaa.in/viz-bin/votable?-source=J/PASP/121/1180http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/PASP/121/1180GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/PASP/121/1180/table3 (Field list)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/PASP/121/1180/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/PASP/121/1180/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/PASP/121/1180/table3?GETtext/xml+votable180.050000true0.090.00.0055555555555555566/879 1144 2244 3054 3394 3649 4095 4959 5378 6260 7554 7809 8192 9135 9400 10753 11246 11586 11841 13215 13512 14516 15746 16001 16444 17754 18006 18857 19109 19456 20419 20556 21913 22165 22890 23142 24435 24736 26198 27049 27301 27648 28812 30105 30357 31082 31334 32691 32768 33150 33405 34635 34850 35639 35936 37310 37565 39751 40016 41342 41597 42891 43042 43773 44192 45502 45757 46907 48007 48272https://cdsarc.cds.unistra.fr/viz-bin/moc/J/PASP/121/1180?format=asciiOpticaldefaultJ/PASP/121/1180/table3Field listrecnoRecord number assigned by the VizieR team.
