This image is a stack of 10 x 1200sec subs at F7 and 14 x 900sec subs at F5. I used the 'Distorsions between images' option. No flats or dark frames (how?) Both OTAs were using an Orion SSpro camera:

Two 10in SCTs F5 and F7!

It looks like the distortions from F5 and from F7 are too different, even for that option. May you post the two separate images?

That's interesting. Using an improved algorithm it was possible to obtain the following result:
It's still not perfect (the "double stars" in the corners now look like "coma").
The correction is now included in SP4, if you like to receive the prerelease please write me by PM ore email.
Here is an animation of the distortions between these two optical systems:
