To get the charts (it is freeĪtlas showing 5800 one-degree fields up to 12.5 magnitudeĭeep sky objects, one has to know exactly where to look at. To plan a quick session with bright and easy objects. The A maps are the index to B and C maps and show a This set together with the A-maps (the project index) constitute a perfect handy atlas Similar to Uranometria, although with more stars. Reaches 11 mag with a linear scale similar to Sky Atlas 2000 but a detail level Magnitudes between main and secondary stars of 1.0 to 1.9 magnitudes, and C:ī-maps set is a standard-alone atlas, that For instance 1C indicates a disproportion in Galaxy clusters ( all Hickson's and some Abell's ) The 12.5 magnitude ( 29,000 variable stars )ġ6.5 mag), the stronger radiosources and a selection of LDN / Barnard ( 1850 dark nebulae )īrighter than 11th magnitude ( 35,000 double stars ) SH-2, RCW and other catalogues for bright nebulae (no LBN because of (from the NGC/IC project), removing discarded objects 15 toĪvoid cluttering), so there are around 37,000 galaxies plotted. It shows galaxies up to 15.5 magnitude from PGC (unlabelled from mag.Preserving a constant value in the whole atlas It shows stars up to 12.6 magnitude, quite good for the map scale,.1º = 2.5 cm (quite good scale do not shrink the.Includes 25, 90 and 661 charts (A, B and C sets), showing the night sky in aĭetail level larger than the Millennium Sky Atlas.
