Sentence Correction (SC) | Re: The cameras of the Voyager II spacecraft detected six small,

If the sentence excluded the part ~previously unseen moons circling Uranus~ then in that case the usage of WHICH would have been correct? Am i right as then the use of which would directly refer to the the cameras.

Please ignore the meaning of the sentence, i just want my doubt of using WHICH to be clarified here.

Please help here.

Thanks in advance
