Description:
The constellation Auriga is host to a wide swath of Ha emission nebulae visible during the winter in the Northern Hemisphere, including IC405 (Flaming Star Nebula), IC 410, IC 417, and NGC1931.   In this cropped version of the original widefield image, IC405 is on the left, and IC410 is on the right.  Please check the larger sized images in the links above for more detail.  More information about this interesting region, including the origin of the star AE Auriga that is responsible for the blue reflection component of IC405, can be found on Rob Gendler's site as well as on the APOD site.
