Thanks for the comments, guys.
The whole shot is reconstructed using HD footage except for that little bit of sky. I was originally going to use GOUT for this shot, because it has a pan added to it, but after I managed to get rid of a pan in the Falcon leaving Mos Eisley shot, I decided to try with this one as well, so first I got rid of the pan roughly, then I stabilized the footage. Then I created an HD matte of the original background using screenshots from the SE and GOUT and than I rotoscoped R2 in from the stabilized footage, added grain to it and then I recreated the wipe from the previous shot.
