NGC 3585

NGC 3585 is an elliptical galaxy in the constellation Hydra about 66 million ly from Earth. It spans roughly 130,000 ly, about the width of our Milky Way. It is receding from us at about 1,399 km/s.

Because its light is 66 million ly from home, you are seeing NGC 3585 as it looked roughly 66 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.
