NGC 1684
NGC 1684 is an elliptical galaxy in the constellation Orion about 207 million ly from Earth. It spans roughly 150,000 ly, about 1.5 times the width of our Milky Way. The light reaching us tonight left it about 207 million years ago.

Because its light is 207 million ly from home, you are seeing NGC 1684 as it looked roughly 207 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.
