For Orions shoulder to have any spatial significance youd have to be light years away, in which case you wouldnt see anything on fire which wouldnt be on fire anyway cause its in space! And whats a c-beam?!?
"Orion's Shoulder" is not the shoulder of the familiar constellation, but rather - something else, off of which one could, indeed, see ships on fire.
"C-beams" must be really fascinating-looking things.
Etc.
That's all you need to know to enjoy the scene.

The ships could have been in orbit over earth or another planet in our system where they were clustered around the shoulder of Orion.
A c-beam I always imagined to be some sort of beam-of-light weapon, like a laser or particle beam or something. c is used to denote the speed of light in Einsteins famous equation: E=mc^2.
