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.
In order to produce the color image seen here, I worked with data coming from 2 different photographic plates taken at Palomar Observatory between 1986 and 1989. The original file is about 31.1 Megapixels with a resolution of about 1 arcsec per pixel. The image show an area of sky large 1.6° × 1.5° (for comparison, the full-Moon is about 0.5° in diameter). This image is a composite from black and white images taken with the Palomar Observatory's 48-inch (1.2-meter) Samuel Oschin Telescope as a part of the second National Geographic Palomar Observatory Sky Survey (POSS II). The images were recorded on two type of glass photographic plates - one sensitive to red light and the other to blue light and later they were digitized.
