The Pacman Nebula is an emission nebula located in the Cassiopeia constellation.
This nebula gets its name from a character in a popular video game.

This image was taken with the OSC (one-shot-color) CCD camera I used for a short time. I really liked the camera but decided that it would be even better if it were monochrome and had color and narrowband filters. So not long after this image was taken, I did obtain a mono CCD with filters.

Below and to the right is a different version of this nebula done with the monochrome camera and a hydrogen-alpha (Ha) filter. The Ha filter really brings out the glowing red hydrogen gas that makes up the bulk of the nebula. But the above image, being strictly in optical light, is closer to what the human eye would see.
