This was the first "long-exposure" I took with a digital camera, the Fuji S1. Stacking five 30 second exposures gave me a three minute stacked image guided on a Losmandy GM-11 with an ST-4 autoguider. The image below was taken the same night, but with film. Note the subtle difference in tonal values pluse the detail differences. Same night, same mount and autoguider.

The differences between film and digital become apparent when comparing detail in the head of the comet and in the tail. I found the digitalto contain more faint detail than the film image. After this session I began to slowly phase out my film work.
