Camera was focused using Live View. Raw images were converted using Canon's Zoom Browser EX. Converted images were calibrated, aligned and combined with ImagesPlus. The f/8 and f/2.8 sets of images were processed separately. These images were stacked in Photoshop and a layer mask was applied to reveal the finer detail in the f/8 image. The final image was adjusted in Photoshop.


This was taken on 8/8/10 and 8/12/10 at the Nebraska Star Party. Seeing was good. Humidity was high the first night with fog appearing after 2:00 AM (a rarity for this area). Temperature: 70F
