With such images available, where do I go to view full HD pictures of the moon?
There isn't such satellite for that. Satellites are not for entertainment, but research. Making satellites is expensive, that is why there is so few.
Wrong, the Lunar Reconnaissance Orbiter
provides great hi-res images of the Moon.
There's only one thing lacking in those images - colour. The Moon isn't utterly black&white, there are subtle colour variations depending on mineral
makeup of the terrain.

I wonder if they doctored the rings image?
Raw images are rarely suitable for public releases (although they are made public at sites like saturn.jpl.nasa.gov...
), so there is
almost always some editing and photoshopping wizadry involved. For example, for this image, they combined the rings from a low-exposure shot
like this one
, and the Earth and the faint outer rings from
a long-exposure shot like this one
. There's also the issue
of alignment of the rings and the Earth from frame to frame, due to the fact that Cassini moves some distance between taking pictures. Based on my
experience on making my own colour composite of this image, NASA had to align the rings and Earth in separate images, then combine them together.
Anyhoo, it's not what I'd call doctoring, but rather using various techniques to overcome technical issues (like exposure, alignment, digital noise,
cosmic particle streaks) and presenting a nice-looking picture to the public. Everything you see there is real, and similar to what you'd see with
your own eyes (despite what GaryN says).
