Aristarchus Crater has long been a much debated enigma on the Moon.
Yet whenever you see pictures and try to get close in for details,
the area is a total white out, with no detail. It is supposedly because of
its brightness. We will discuss the rumors and stories of Aristarchus
further down. The image above is taken from LICKOSB9 As you can see
the area is devoid of any gray pixels, leaving a totally white splotch.
Below is the same area on LICKOSBA. Again we see the totally white
splotch. You will find this in all of the lesser quality full moon images on
the web.

If you haven't already seen the Full Moon that Mike took where this clip of
Aristarchus is a small section, you can do so HERE. The picture above is
Aristarchus Crater clipped from an image taken with a 10" Telescope
in the UK. Compare this image to the high resolution image from
the Clementine Satellite below and remember that this is a 10" telescope
image.
You will notice the symmetrical dome like structure of the "crater" as well
as the bright blue glow that literally lights up the surrounding area!
The overall effect is that of plasma energy emitting from the dome,
or at least very bright light.

Both the Clementine and Mike's image show the beautiful "Electric Blue"
color of the crater and both show dome like structures, with a bright
center. Both also show that the luminescence covers the surrounding area.

Now we have a third confirmation... this one is also from the UK
