About this image

Had initially contemplated capturing an hours worth of data for each filter (Ha & OIII) using fifteen minutes exposure time,but having captured the Ha set cloud had set in just as the camera downloaded the first of the OIII set resulting in the session ending there and then. Rather than waste the images I took one image from the Ha data and combined it with the OIII image in Maxim DL4 to produce this bi-colour image (Ha,OIII,OIII) and processed in Photoshop CS2.
