Just to be clear, the Cygus loop (also known as the veil nebula) is a supernova remnant, while Barnard's loop is a broad galactic region of ionized gas and dust.
Here is an image of the cygnus loop using a partial "Hubble pallet", which in this case consists of filters for hydrogen alpha emission (green in this instance), and triply ionized oxygen (blue).

Here is my image of the eastern veil Nebula:

"In short, Meyer has shown that his first disastrous book was not a fluke: he is capable of going into any field in which he has no training or research experience and botching it just as badly as he did molecular biology. As I've written before, if you are a complete amateur and don't understand a subject, don't demonstrate the Dunning-Kruger effect by writing a book about it and proving your ignorance to everyone else!
