Hello Sterling:

35 cm on the Lunar surface? That would be Totally Unbelievable! A camera
connected to a telescope on Earth that can distinguish a foot by a foot
(35cm ) square on the moon through the Earth's atmosphere, they could
actually take some nice pictures of the old Lunar modules and stuff right
from Hawaii. I know technology has progressed but that would be awesome!

If Dawe's Limit ("theoretical" in quotes) has any relevance to the
telescope-camera combination. The very best that could be done would be
about 60 meters x 60 meters per pixel. But their pixels in the image with
atmosphere and all, resolution appears to be over ten times worse.

I took a Sear's Stanley tape measure to the picture of the explosion from
the Canada France Hawai'i Telescope which they say is 200x200 km, and from
that get that the flash is about 15 kilometers by 15 kilometers, not your 8
by 8 meters (don't follow how you got that (there's a lot of theoretical
atmospheric and optical limits beyond me to deal with since the camera has a
big reflector and a quarter of a million miles in front of it.) Sorry about
the low tech check.

As a cross check, in their published image there are indeed about 22-23
pixels up and down and across - sometimes.
That would say that it is about 11.5 km x 11.5 km, only 2 million times more
area than you suggested. (400 x 400 pixel image size, the blast covers
(23/400*200,000)^2). Note how many features look like squares and
rectangles (better in my enlarged image below).

Then, if 15 km equals 23 pixels, they are getting 650 METERS (OK maybe as
low as 450 meters) per pixel, not 35 CENTIMETERS per pixel and Big Brother
can't read the license plates on the Lunar rovers yet.

As to the "square shape", I think it's like looking at clouds on the
Oklahoma plains and you see what pleasures you. There appear to be spashes
around all the edges to me and some nice new SMART-tektites to go-n-get. I
can easily count 30 pixels up and down in some parts. But maybe you've got
a good theory there, nothing proves it's not a square.

I've posted an enlargement of the explosion showing with the individual
pixels posted on the CFHT page here:
www.diogenite.com/smart.JPG
for anyone curious about the shape of the explosion, which clearly shows
rays of light like splashes and, maybe or maybe not, coincidentally, four of
them defining Sterling's "square". It is even more coincidental that the
square would happen to be perfectly setting horizontal in the image - or
yikes, that could that be enhancing a perception or illusion. Try rotating
it in your image viewer. Who knows. The Shadow?

Best wishes, Doug
PD, IR might be the favorite choice since it gives better night vision, so,
I guess we all forgot to put the Russian goggles on our scopes and binocs...
In any of the articles did it actually say someone saw real time a flash in
the visual light's range?
