Wow! Great moon shot.

Re Lightroom: I noticed a big improvement when upgrading from 1GB to 2GB of memory. The PC is winXP on AMD 4200 X2. So it's a bit old but still hangs in there with the extra memory.

I'd say it passed. Pretty sharp for 1/50" and no star drive. How did you avoid vibration - lock up the mirror? An old trick with film cameras was to open the shutter on bulb with a card in front of the lens until things settled down and use the card as a shutter, putting it back in front before closing the camera shutter.

Yes, mirror lock up. But I do find it troublesome with vibrations, I think the slight blur or softness along the upper edge is shake blur. I'd need a 3000$ tripod to get away from that, I'm afraid.
