[Marvel] If Nightcrawler was watching a TV show, could he teleport onto the set?

As far as I know, Nightcrawler can teleport anywhere as long as he can see it or has been there before. So if he can see the set of a Tv show through the Tv, can he teleport there? What if it’s an old rerun from the 80’s and the set doesn’t exist anymore?

Every version of Nightcrawler, has a limited teleportation. He likes to be able to see where he is teleporting to or else he could teleport into a wall be get hurt. Its a pure safety precaution. When he teleports, he's literally jumping through a different dimension. But he's still physically going through it, hence the need to be able to see when to stop. To the rest of the world it happens in an instant. 

So no, he cannot just teleport halfway around the world, despite being able to see it. He has bent the rule a little bit, by making a lot of frequent jumps to get to his final destination. 

This also means, if he was stuck in a dead spaceship somewhere in space, far away from anything, he cannot just teleport back to earth, since he has been there before. 

Perhaps if you add some magic trickery of something else boosting his powers or something, you can rewrite the rules. But as it stands traveling long distances requires multiple hops, and he's usually super exhausted by the end of it. (Think Ant man growing big).
