Over 2 degrees in extent, this large nebula was too large to fit within the field of my 12.5 inch, so I concentrated on the "Gulf of Mexico" region. The images were taken on hypered PJ400, carfully guided with the SBIG ST4 Autoguider. Then they were scanned at 2700dpi, and combined with multiply in Adobe Photoshop. A lumicon off axis guider was used, and comma corrector.
