Was it replaced with CGI? Odd, since there is a phaser strip on the lower part of the ship.
The Tamarian ship is "above" the Enterprise
, which requires the beam to travel at an upward angle - the lower saucer phaser strip could only shoot to a max inclination of 0-degrees (straight ahead) before carving into the saucer itself.
Ahhh, I understand. It has been years since I've seen the episode, so I couldn't remember what was happening in that section. So I suspect they've changed it to a shot coming from the topside of the saucer?
Hopefully the replacement looks good.
