When the crew are gathered in the observation lounge, the starfield is still, except during the close-up of Worf, when the stars suddenly start moving.
The entire premise of this episode is ridiculous. All the hemming and hawing about the unstable holodeck program was pointless. All the crew had to do was wait for the colonists to go to sleep, and gas/stun them. While they were out, reboot the holodeck, they wake up, problem solved.
