English: Equirectangular plot of declination vs right ascension of the Messier objects relative to the modern constellations, coded by type and apparent visual magnitude, with a dotted line denoting the ecliptic. Note that the right ascension axis increases from right to left to approximate the view of the night sky. Messier object data is from http://messier.seds.org/dataDec.html . Constellation boundaries are derived from ftp://cdsarc.u-strasbg.fr/pub/cats/VI/49/bound_18.dat with Ursa Minor's corrected to reach the north celestial pole. The Milky Way bitmap is from http://svs.gsfc.nasa.gov/vis/a000000/a003500/a003572 (low-res magnitude 5 version). Thanks to Timwi for 4-colouring with each quadripoint having all colours.

Equirectangular plot of declination vs right ascension of the Messier objects relative to the modern constellations, coded by type, apparent visual magnitude and distance, with a dotted line denoting the ecliptic, by CMG Lee. Note that the right ascension axis increases from right to left to approximate the view of the night sky. Messier object data is from http://messier.seds.org/dataDec.html . Constellation boundaries are derived from ftp://cdsarc.u-strasbg.fr/pub/cats/VI/49/bound_18.dat with Ursa Minor's corrected to reach the north celestial pole.
