Through the Looking Glass - S1-E17
Visible crew/equipment: This episode begins in the galley, and while everyone's eating and talking the camera moves around the table following their conversation, and when the camera passes Rygel, or even Zhaan, we can see the head and/or movement of the puppeteer behind Rygel.

Visible crew/equipment: After the four Moyas come together in the same plane of existence everyone appears at Pilot's console, and when Pilot says, "I fail to see the source of your amusement," we can see the puppeteer rods under one of Pilot's left arms.
Through the Looking Glass - S1-E17
Visible crew/equipment: After Rygel, D'Argo, and Aeryn vanish, when John's in the command center talking to Pilot, when it cuts to Pilot in his den just as Pilot says, "Officer Sun in maintenance bay 3," we can see the puppeteer rod under Pilot's arm as it moves about.
Chosen answer: It's never explained. John mentions a theory that his less technologically developed craft simply interferes with the wormhole less than the "superior" Vipers, but they never make a concrete determination on that point. But we also have to take into account the fact that Moya traverses wormholes with no ill effect as well.
