Wacka Wacka Wacka…. or shall we say NGC281, also known as the Pacman nebula. NGC 281, IC 11 or Sh2-184 is a bright emission nebula, part of an H II region in the northern constellation of Cassiopeia and is part of the Milky Way’s Perseus Spiral Arm. It lies 9200 ly. from us. There are many pictures available of the bright red emission area. I aimed for a big integration time of over 20 hours to make the surrounding very faint brown molecular clouds visible. The image is a combination of Ha-O3 narrowband and LRGB.
