witches broom veil bi colour - a photo on Flickriver

            part of the same supernove remnant known as the Cygnus Loop, or Veil Nebula - along with the 'beckoning finger' or 'bat' or 'fang' nebula (see previous image taken recently) there is this one, the 'Witches Broom' nebula - as you can see it has a certain broom-like quality :P

This is another bi-colour narrowband shot, h-alpha and OIII (oxygen3) combined as Ha-OIII-OIII for red green and blue channels respectively.
