NGC 281 - The Pacman Nebula!




Imaged on Saturday 4th October 2014

Despite the weather not being quite as good as hoped (moisture/haze) and the moon in attendance, I think this has come out reasonably successfully....

Spanning 80 light-years, NGC 281 is an area of star formation in the constellation of Cassiopeia and part of the Perseus Spiral Arm that lies around 10,000 Ly away.

Features include the open cluster IC 1590, the multiple star HD 5005, several Bok globules seen in silhouette against the nebula, a diffuse Ha red-glowing emission nebula and large lanes of obscuring gas and dust.

Colloquially, NGC 281 is also known as the Pacman Nebula for its resemblance to the video game character.

The nebula was discovered in August 1883 by E. E. Barnard, who described it as "a large faint nebula, very diffuse."

Pac-Man was an arcade game developed by Namco and first released in Japan on May 22, 1980. It was licensed for distribution in the United States by Midway and released in October 1980.

Immensely popular from its original release to the present day, Pac-Man is considered one of the classics of the medium, virtually synonymous with video games, and an icon of 1980s popular culture.

When Pac-Man was released, the most popular arcade video games were space shooters, in particular Space Invaders and Asteroids. The most visible minority were sports games that were mostly derivatives of Pong. Pac-Man succeeded by creating a new genre and appealing to both genders.

Pac-Man is often credited with being a landmark in video game history, and is among the most famous and highest-grossing arcade games of all time.
