Slightly different pixel scales

[cardiofuse]

I have been shooting a target and have a batch of subs (LRGB) of the same target but slightly different pixel scales (1.13 and 1.23 arc/pixel).  How hard would it be (or by what process) would I go about scaling and aligning these "sub masters" ?

I'm just not sure of the best way to approach this.

StarAlignment will scale the image(s) it is working on by default, so all you have to do is pick one as the reference and register the others to it...
