IC410 is an emission nebula in the constellation Auriga. It surrounds the small open star cluster NGC1893, seen in the center of this image. The nebula contains complex patterns of hydrogen and oxygen gas that glows when excited by radition from nearby stars. The two tadpoles
visible in the lower-right appear to be early star-forming areas. Their tails are both distorted in the same region and direction.
This image was exposed using narrowband filters to make the stars less prominent and better show the tadpoles.
