Cygnus
Photographed by Fred Lusk on July 25, 2003
From Courtright Reservoir, Fresno County, CA
 
Description:
This image shows the constellation Cygnus and its signature nebula NGC 7000, the North America Nebula. This image (and a few others I took during Summer 2003) convinced me that I needed to find a better film than Kodak Royal Gold. After some research, I learned that no color print films have the red and blue sensitivity needed to show nebulas in all their glory. The best color films for astrophotography turned out to be Kodak EliteChrome 200 and 400 and Fuji Provia 400. These color slide films produce outstanding reds and blues and have excellent reciprocity characteristics for long exposures. I have used these films since 2004, although the Kodak films went out of production in 2012. Fortunately, the Fuji is still available.

Exposure Details:
Boot's Camera handled developing and scanning the negatives. The rest of the exposure data is missing, but this is likely what I did: [1] Film was probably Kodak Royal Gold 100. [2] Exposure was probably around 30-minutes. [3] Lens aperture was probably f/4 or f/5.6.
