Pacman Nebula is here

 

Pacman Nebula (or NGC 281), is a bright emission nebula in the northern constellation of Cassiopeia and is part of the Milky Way's Perseus Spiral Arm. It is estimated it lies 9200 ly. from us. Colloquially, NGC 281 is also known as the Pacman Nebula for its resemblance to the video game character. E. E. Barnard discovered this nebula in August 1883, who described it as "a large faint nebula, very diffuse." (dixit Wikipedia)
