| Notes: |
I would like to thank Dave Dockery
for his assistance in processing this image. This is a replacement of my "first
light" image taken on 7-1-04 with the Canon Digital Rebel camera. The guiding
and focus are better on this image. You can still view my inaugural attempt here. Compare these attempts with my best film
image. This shot clearly shows not only the central star, but 3 other stars within the
nebula. This image was taken without filters during a 3/4 full moon. |
