There weren't any telescopes/rockets at the time.

Yes. A small number of galaxies have been named after individual people. Usually, the named individual was the person who discovered the object, or brought attention to it, or who first studied it scientifically. Normally they would be astronomers, or at least hobbyists.
No planets have been officially recognised outside our galaxy, though more than 500 exoplanets have been identified outside our solar system. Our nearest galaxy is too far away to detect such planets, though we can assume that it will contain several millions of planets based on observations within our own galaxy.
The first time an object was viewed as a black hole by most astronomers was in 1971. Prior to that, most astronomers were skeptical such an object even existed, let alone that one had been detected.
Many people consider the first astronomers to be the first humans that ever looked up at the night sky and wondered what was really up there. So cavemen were probably the first astronomers.
The joke in which a blond says she does not know which is bigger, the Earth or the galaxy, because she has not been to the galaxy is a mockery of blond people. The Earth is in the galaxy, so she has been to the galaxy. The joke implies that she isn't smart enough to realize that she is in the galaxy.
It's fair to say that our own galaxy was discovered first.
