Processing Comments:  Ha-Red blend perforned  in Photoshop CS/3.  Ha-R/G/B assembled in Maxim DL.  Further processing, including data stretching (curves/levels), Shadows/Highlioghts,  High Pass filer used in PS CS/3. As with the Ha image, the image was challenging due to the presence of a full moon, manisfestd by some backgound noise.
