You mean this shot?
I thought it was this shot as they enter the room after Parker says the line "OK, check the bottles" The camera moves over to focus on the tracker. I think I got mixed up there:
The sequence was really cut back to the bare minimum. The unused insert tracker shots, I think, would've added to the tension even more.
Agreed. Don't get me wrong I understand why Alien was cut and edited the way it was and to me, it works like a charm.
But I'd still like to see the original intended graphic cut of the film that has been talked about over the years in various articles/interviews especially the deaths of both Brett & Parker. Veronica Cartwright says in issue 158 of Famous monsters of filmland that the fronts and backs of scenes were also cut just leaving the middle segments. I'm a sucker for deleted and alternate scenes of movies especially the Alien movies.
