Ha images were focused, aligned, and combined in MaxIm DL. Color images were focused, captured, and aligned with ImagesPlus. The mosaic was composed in Photoshop CS2. The color and Ha images were then aligned in RegiStar and combined in Photoshop (pasting the color image over the Ha background, blurring the color image, and blending using Color mode). The final image was adjusted (Levels, Curves) in Photoshop CS2. Gaussian blur was applied through a layer mask smooth the image.
