This represents my fourth or fifth attempt on
this object. I consider this object to be rather difficult and was very
pleased this time with the results. There was absolutely no light pollution
at the chosen site. It should be noted that the scanning process seemed
to bring out more blue in the background stars than is evident when viewing
the slide. The slide shows excellent contrast between the dark sky and
the Crescent Nebula. The digitized version approaches the contrast level
of the slide although it is hard to beat a slide. |
