NGC 3547

NGC 3547 is a barred spiral galaxy in the constellation Leo about 74 million ly from Earth. It spans roughly 38,000 ly, about 38% of our Milky Way's width. It is receding from us at about 1,513 km/s.

Because its light is 74 million ly from home, you are seeing NGC 3547 as it looked roughly 74 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.
