Goofs

Cain sends the Pegasus through a bright starfield after Baltar's base ship. According to the dialogue, the Pegasus is traveling alone at this point. However, the exterior shots in this sequence show the battlestar being followed by at least half a dozen other ships. (These shots are actually of the Galactica leading the fleet through the Nova of Madagon, from "Saga of a Star World"). In the "Living Legend" episodes from which Mission Galactica was derived, the sequence is different and does not show this goof.

Part of the explosions on board the Galactica are obviously stock footage that was shot with anamorphic lenses and not properly desqueezed for the series' 1.35:1 aspect ratio, which is apparent from the fireballs' strange elongated appearance.
