IC 410 Tadpole Nebula in Auriga

Picture taken at Sandsli, Norway. December 9, 2020
The Tadpole Nebula is the oval shape covering most part of the right half of the image.
It is more than 100 light years across and lies about 12000 light years away.
It got its name from the 2 tadpole-shaped structures near the center of the image.
These relatively dense streamers of material trailing away from the nebula's central regions are believed to be active star forming areas.
