A four panel panoramic mosaic of Auriga, IC 405 & 410

This image shows a wider field view to Auriga Nebulae, IC 405 and 410.
Also Sharpless 232, Sh2-232, IC 417, Messier 38 and NGC 1907 are seen in the image.
Image is composed from four panels and covers about nine degrees horizontally, that's equal to area of 18 full Moons side by side in the sky. There are not many images around to show the whole nebula complex.

An older study about the scale in a sky can be seen here:

mage is in Natural color palette from the emission of ionized elements, 
R=Hydrogen + Sulfur, G=Oxygen and B=Oxygen + Hydrogen.
