Tony,

Those are mind boggling images.  It gives me a sense of the imensity of our universe.  Thanks for posting it. 

<<<     With thanks and gratitude to Mike Cook for his generous help in the pursuit of better signal to noise technique, I have reprocessed the 120 minutes worth of exposure of B&W M-51 that I took this last DOM. (By the way, all this detail does NOT show up in a bright moon, CCD or no CCD...) >>>

For either CCD or film, the SNR is primarily limited by sky background, so, the darker the sky the better the result.
