NGC 704B

NGC 704B is an elliptical galaxy in the constellation Andromeda about 220 million ly from Earth. It spans roughly 70,000 ly, about 70% of our Milky Way's width. The light reaching us tonight left it about 220 million years ago.

Because its light is 220 million ly from home, you are seeing NGC 704B as it looked roughly 220 million years ago. The photons left before that much of history had passed, and are only now reaching us. This distance is estimated from the galaxy's redshift, so the lookback time is approximate.
