Once positioned in space, the Hubble Space Telescope will capture light from sources twenty times fainter compared to those that can be detected by ground-based instruments.

(A) compared to those that can be detected

(B) compared to those they can detect

(D) than those that can be detected（D）

(E) than those detecting

答案是D,没有问题. 我想问 : D中的that是指代those吧, 那把(D)中的that省略改成 than those can be detected对吗?

than those can be detected

对的

我有另外一个问题

light不可数为什么用those？而不用that？

完整句子: the Hubble Space Telescope will capture light from sources (that are) twenty times fainter than (the Hubble Space Telescope will capture light from) those that can be detected by ground-based instruments.

现在就很明确those指代什么了
