Equidistant projection onto a cone (below latitude 50 N) or a cylinder (50 and 60 N). For cylinders, undistorted parallel is at the Belt of Orion, for cones, there are two such parallels at 8 degrees from the Belt. The Bright Star Catalogue has been used for the maps 0 mag to 5 mag (Betelgeuse shown at its maximum light), the original Hipparcos for 6 mag and 7 mag (Delta Orionis is too faint in the Czech version, due to a bug in the map_bsct programme; the bug has been corrected in October 2010 and another map sets renewed). The limits are for the amounts of light entering the eyes of observers, i.e., starlight is attenuated by the atmosphere.
