This shot appears to be new footage due to the mist surrounding Bansheera
I'm unsure of some star shots that Simon saw while looking in his telescope but all shots of the asteroid is Sentai footage.
All footage of the Rangers fighting Batlings has been removed.
This shot of the Red Ranger is I believe a recycled Sentai shot.
This shot of Olympius and the Rangers is actually Sentai footage. In Sentai footage, they're actually firing what you would know as our "Thermo Blasters."
All Olympius stuff in Mariner Bay and all zord footage is Sentai footage.

Sentai info comes from GoGoV Episodes 29 and 30
