*mag:  light magnitude= >  up to mag +3-4 stars are visible nearby cities with the naked eye, in very dark areas the seeing limit can reach up to mag +6-7. The more higher numerical value is given, the more weaker are the objects. E.g. - 4,7 mag, Venus glittering; - 1,0 Sirius, brightest star; +3,5 M31 Andromeda, pale shiny oval.
