And they don't use visual range of photography for nebulas. They take pictures applying the three primary colors of light assigned to the composition of the nebula. Red shows emission from singly-ionized sulfur atoms. Green shows emission from hydrogen. Blue shows light emitted by doubly- ionized oxygen atoms. So, if you were to look at the nebula it wouldn't look like the picture shown.
