Sharpless
232 in HaRGB
-----------------------------------------------------------------
From SKYFACTORY.ORG:
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.
