NGC 281, The Pacman Nebula
I debated whether or not to post this one, since it needs a lot more data, and I had some instrument problems that night. But it doesn't look as bad as some I've posted, so I thought, why not?
From Wikipedia:
http://en.wikipedia.org/wiki/NGC_281
NGC 281 is an H II region in the constellation of Cassiopeia and part of the Perseus Spiral Arm. It includes the open cluster IC 1590, the multiple star HD 5005, and several Bok globules. Colloquially, NGC 281 is also known as the Pacman Nebula for its resemblance to the video game character.

"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!
