Thanks Ray and Saturnino, the Moretus (2 pane) image was the most turbulent with wavey seeing but it is amazing how software can show so much detail by stacking and sharpening.
I use AviStack1.81 for aligning and stacking and Regx5.1 for waveleting and PS CS3 for contrast (soft light), despeckling and hipass sharpening and final noise reduction.
Avi is Mpeg2 but shows reasonable quality.
