Description:
The
constellation Auriga is host to a wide swath of Ha emission,
including the regions of IC405 (Flaming Star Nebula), IC 410, and
IC 417 shown above. IC405 is the statuesque nebula located in
the
lower left corner and extends upward, like smoke from a flame.
IC410 is located in the upper portion of the image, just to the right
of center, and IC417 is located in the lower right hand side. I
have previously imaged these nebulae separately, with more detail
provided in
the following links: IC405, IC410, and IC417.
