FOV = 96 x 65 arc minutes

This faint emission nebula lies about 12,000 light-years away in the northern constellation Auriga. Doubly ionized oxygen dominates the core of this region. Notable near the 10 o'clock position in this widefield view are two relatively dense streamers of material trailing toward the nebula's central regions. These "tadpoles" are sites of ongoing star formation. Each one is about 10 light-years long.
