Doug,

Thanks, but anyone with a stable, accurate mount and CCD should be able to do the same. After All I only used a 6" telescope!

I've had discussions several times in the past on why *very deep* images are possible from light polluted skies, suffice to say it centers around signal and noise.

For example, DSLR's can provide simply wonderful imagery but are often limited by noise, dynamic range and QE. I own a number of DSLR's but I could not reproduce this shot with say, my Canon 5D as it would hit a sky fog limit long before I could extract any useful signal.

Under dark skies the situation is very different. I am often amazed how well DSLR's perform, and the ease with which they can be used....as they say, horses for courses
