The appropriate opacity should be 100 / layer number.

e.g.
Layer 6 - 16% (Topmost layer)
Layer 5 - 20%
Layer 4 - 25%
Layer 3 - 33%
Layer 2 - 50%
Layer 1 - 100% (Bottommost layer)
We are talking focus stacking here- but for noise you can go another 2 layers on what you have there,14% and 12% respectively-Ken
