NGC 149

NGC 149 is a lenticular galaxy in the constellation Andromeda about 223 million ly from Earth. It spans roughly 59,000 ly, about 59% of our Milky Way's width. The light reaching us tonight left it about 223 million years ago.

Because its light is 223 million ly from home, you are seeing NGC 149 as it looked roughly 223 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.
