I have been planning this project since January of 2003. It has taken me approximately two months to complete a mosaic of 7 different composites. The conditions seemed never to be just right for this project. Then, in late January 2004, I started to have my openings. The combined exposure time of this image is just short of 16 hours. There were a total of 312 individual images consisting of over 2 gigs of data. I should of tracked the number of hours it took to process this final image, but I didnt. Actually, it kind of scared me before I started. If I were to guess, probably around 120-150 hours of processing time.
