It's a very nice looking image. For anyone who goes to see the full-sized image and is using a display with less than 1200 pixels vertical make certain that you scroll downward to actually see the surface of the moon, since the top left corner is just empty, black space and that's where Astrobin places you when you first display the image.

Very nice. The full res image has some strange artifacts here and there. What was your processing like?

Hi and thanks wink.gif ,

 

@james7ca: yow yes, indeed, you're right thanks for the tip. That could have been confusing for some people after cliking on the full!

 

@Borodog : my processing is wavelet with ASTRA images and then sharpening in Photoshop CS.
Could you please show me exactly where you seem to see "strange artefacts"?

For example, in the middle of Clavius.

@spereira : sorry for the wrong section and thanks for your action wink.gif  !

 

@Borodog : I did took a closer look at it and I'm afraid I still don't see any artifact confused1.gif ?

Perhaps it's just a trick of the sharpening. The little checkerboard patch directly in the center looks strange to me, but looking at it closely I would probably not call it an "artifact."

Oh, you mean this?

If I compare with picture of Lunar Reconnaissance Orbiter Camera (LROC) above, the checkerboard is there wink.gif  .
