You gotta be happy with that Paul,
You can stack using Photoshop. I have not tried stacking large images with Registax, but I would hesitate to do so.
To stack in Photoshop just place each image on a seperate layer. Use difference blending to line them up, then use normal blending on each layer and change the opacity on each layer to subsequent less ratios in the order of...
1 = 100%
2 = 50% (1/2)
3 = 33% (1/3)
4 = 25% (1/4)
5 = 20% (1/5) etc.....
Alot of DSLR uses use Images Plus for stacking & aligning, but I'm too tight to buy it. PShop seems to work fine.

Hope this helps
Cheers
