I was tickled to get this series of photos. Pluto is on the edge of my Canon G2 and 8" scope's capabilities. I cannot see it with my eye. I have to trust that it's there based on the brighter stars I can see in the field of view. The light from Pluto is just barely above background noise.. The only way I KNOW I have captured the little bugger is by taking pictures of the same spot in the sky on successive nights and looking for a “star” that has moved. I got it! Pluto’s diameter is  about 50% larger than our moon, but it is so far away that it appears 47,000 times smaller, and by the time the light from our sun gets all the way out there and back to us, it is over 320,000 times dimmer.

between 4 & 6 pictures were averaged together for each day, then the resulting 4 photos of each day were aligned with each other and the brightest elements of each picture were used to make a final composite photo, then brightness and contrast were enhanced
