Sh2-232 (Sharpless 232) is the biggest but faintest member of a complex of diffused nebulas in the Auriga constellation, about 3 degrees from IC405 (the Flaming Star Nebula) and IC410. The other members are Sh2-235 (botton-left respect Sh2-232), the brightest of the group, and Sh2-231 (at right). Less cospicuos in size but not in beauty, Sh2-233 (at far right) completes the picture.
The brightest blue star in the picture is an anonymous A0 star and has a brightness of just 7,1 magnitude.
