Hows this for a different approach!
I grabbed all 15 trial images in this thread, saved them as .bmp's in PS, then stacked them in Registax.
For Wavelettes, I used the 3 bottom sliders only: 2.4, 3.1, 3.8
Then back into PS -
Colour Balance: +2 Red in Midtones
2 clicks on 'Sharpen'
1 click on 'Despeckle'.
This is what everyones images look like stacked together
