Hi there Fast Break... Han may have had one of those Jedi training remotes for other reasons i.e distraction device to get past guards for instance. or to get rid of mynocks lol

I'd say that in conclusion the technique of making one of those floating Jedi training remotes could be of use to Ady when he get's to ANH:HD to fix the bad compositing.

But making use of the footage where luke is swinging a light saber in thin air would be enough to suggest Yoda was teaching him how to use it more effectively without aid of technology but without making it feel like Rocky IV either...But it is probably not for this edit... Star Wars Kid also springs to mind...But I wonder how it would look rendered with a light saber glow and sound effects It might actually be quite good finished....

If anyone from the community wants to attempt a render of it I would be interested in seeing the result...

Timmdiggerm is right technology is way out the mix on dagobah no remotes should be present here and it got cut for good reason.
