Well, I am working on trying to remove the explosion ring from Alderaan for my fanedit, and I can give the 1080p file next week or so, but I cant guarantee it due to the pandemic going on.
I also have a re-composited shot of the grainy speeder drive-by shot in the OOT graciously done by SkyDude over at the Star Wars Trilogy forums which I can give to you aswell.
