17P / Holmes - November 19, 2007 Update

f/11 - 3 x 7 minute exposures


f/7.1 - 3 x 5 minute exposures

I had an opportunity to process the photographs I shot of 17P/Holmes Sunday night (Nov. 18/19). I had shot 5 minute, 7 minute and 10 minute exposures at both f/7.1 and f/11. The f/11 shots produced tighter stars with better diffraction patterns while the f/7.1 shots went deeper. So I'm including two different images. If I had the mental and physical ability to do it, I would like to get another shot (probably pre-dawn) with a mountainside or tree line in the foreground. We'll see.
