Constellation borders

A point of the sky is marked on the chart with a ringed cross, and you say which constellation it is in. A constellation is the whole area inside its official border, so a point between the figures still belongs to exactly one of them, and an exam question about a galaxy or a comet often depends on which. The borders are hidden until you answer. At the first level the point can be anywhere in the constellation, and at the next two it is within 2.5° of a border, where the figures alone are not enough.
