Comments: | This was a long term project as the spring time weather is very variable and changes rapidly. This data took over a month to gather because of the conditions. The light pollution is continuing to get worse and the processing time gets longer and longer to deal with it. I used some of the techniques that were presented at AIC 2006 to help bring out the color and the details. |
