Yes that is the trick.
I usually use 40 iterations or less in CCDstack positive constraint.
Basically Ken's technique is to do several versions at higher and low levels and then combine them in Photoshop as you see fit.
I believe how much decon you can use also depends on the image. A dim image will not take much but one that is stong will take more.
I judge by the star shapes. But if you want detail in the galaxy you could just judge the galaxy only, not worry about deformed stars and then blend in the galaxy sharpening only in a masked layer in Photoshop.
How you do all this in PI I don't know.
