I used one hour each of hydrogen alpha and oxygen III filtered data (15 minute sub exposures). Acquired in CCDSoft with my Epsilon 180ED and STL11000 camera with AstroDon filters. I processed the data in CCDStack, including minimizing a strong gradient in the OIII image, likely due to a combination of Sacramentos light pollution and the Moon. The color was assembled in Photoshop CS using the clipping layers method. Im amazed at the detail revealed in the full-resolution image.
