NGC 281 is a bright H2 (hydrogen/red) emission nebula in the northern constellation of Cassiopeia. NGC 281 is also known as the Pacman Nebula for its resemblance to the video game character. NGC 281 is estimated to lie 9200 light years from us. This was imaged on the 3rd of 3 clear, moonless nights in the Anza Borrega desert 2 weekends ago (the NightFall Star Party).
