No worries, Bill.

My top tips:
1. Brightness =0
2. Gain = 380 (this gives best dynamic range apparently)
3. Adjust exposure on the middle brightest part of the disk so the max on the histogram is about 225 (roughly).
4. Use same settings for all parts of the mosaic.
5. I've been getting away with assembling the mosaic in PS CS3 after wavelets in Registax. Give it a whirl, but if it doesn't work assemble the mosaic on the unsharpened stack.

Good luck!

Al.
