Registax alignment Help

Hello Everyone

I am trying to align and stack a few images I have in Registax but when I select a crater in the center the rest of the image doesnt get aligned and I get a radial pattern moving out from the center crater which was taken for alignment. Is there anyway I can select multiple points to over come this. I have attached an example.
Please help.

Afraid not. Seeing must have been terrible?

The only thing you can do at such times is align 4 or 5 times on different features and combine them into one image in photoshop or similar. You could also select the largest possible aligment rectangle for aligning, but resolution will suffer.
