Sh2-232 is a very dimmed and small diffused nebula in the pentagon of Auriga, about 3 degrees northeast from IC405, a famous and striking nebula in the constellation. A large and round one in center is Sh2-232, and two other small nebula in south west have numbers of Sh2-235 (left) and Sh2-231(right). Sh2-235 is the brightest one in three nebulae, we can capture it only with wide-angled photo lenses.
