NGC 281 The PacMan Nebula
23 x 600 sec Ha + 24 x 600Sec OIII
NGC 281 is an H II region in the constellation Cassiopeia, nicknamed the "Pacman Nebula" for its resemblance to the video game character. Pacman nebula lies about 10,000 light years distant, in the Perseus spiral arm of our galaxy. It is a busy workshop of star formation. Prominent features, besides its diffusely glowing hydrogen gas, include dark lanes of obscuring dust and dense knots of gas and dust - Bok Globules - in which stars may currently be forming. NGC 281 also includes the open cluster IC 1590, of which the multiple star HD 5005 is the brightest member. Its light helps ionize the nebula's gas.
