The Coma figure is not correct. The light-rays should not, repeat: not intersect in the image plane, except for the two rays from the innermost part of the lens. From zones more outward of the center the rays intersect more and more in front of the(paraxial) image plane. That's why you get those larger and larger circles, which is correctly shown in the smaller figure to the right of the main figure.
