This image took a long time to acquire. This is my third seasonal attempt. The nebula is quite low from my location and dogged by light pollution. Added to that the murky winter mist and poor UK weather have played their part. I started the image with the luminance back in October 2005!! There are still some gradients in the image but it got to the point where correcting them further was detracting from what data I had. Overall I am reasonably pleased, although some of the fainter nebula areas have not come through.
