Many THX for clearing up the SD/SSD shot - it bothered me in recent versions, that the group is somewhat broken up or gone missing
On the Vader helmet: ok I got this old comparison, maybe other things aren't spot on either, it just felt weird, that from one shot to another the reflection is moving, without Vader doing something (in the original version he walked some steps from right to left)
So my bad, after a long wait the mind plays tricks on you ;-)
