  • La projection utilisée est une projection centrale (qui préserve les alignements). L'échelle est choisie pour que la "distance" du centre au bord du carré soit ~ 25°. La représentation paraît échelle 1/5 pour une distance de lecture normale.
  • Les positions stellaires et les magnitudes viennent du catalogue d'étoiles de Yale.
  • Les tracés des constellations sont souvent (pas toujours) inspirés de "The Stars - A new way to see them", H.A. Rey, 1952-1980, ISBN 0-395-24830-2.

Cette animation vise à contourner le problème que représente pour la reconnaissance des constellation la très grande différence de visibilité des étoiles, fonction de leur magnitude et des conditions d'observation. Le carré correspond au champ de vision d'un observateur standard. L'impression visuelle est celle que l'on peut avoir au cours d'une nuit étoilée.

  • Central projection used (preserves star alignements). Scale: From square center to edge ~ 25°. This picture seems scaled ~1/5 for a normal reading distance.
  • Star positions and magnitudes are taken from the Yale star catalog.
  • Constellation drawings (often but not always) following "The Stars - A new way to see them", H.A. Rey, 1952-1980, ISBN 0-395-24830-2.

This animation is ment to compensate for the wide differences in star visibilities according to magnitude and visibility conditions, and its impact on constellation pattern recognition. The square corresponds to the field vision of a standard observator. The visual rendering is that of a starry night.
