NGC 1728

NGC 1728 is a spiral galaxy in the constellation Eridanus about 176 million ly from Earth. It spans roughly 64,000 ly, about 64% of our Milky Way's width. It is receding from us at about 4,507 km/s.

Because its light is 176 million ly from home, you are seeing NGC 1728 as it looked roughly 176 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.
