NGC 6897

NGC 6897 is a barred spiral galaxy in the constellation Capricornus about 248 million ly from Earth. It spans roughly 68,000 ly, about 68% of our Milky Way's width. The light reaching us tonight left it about 248 million years ago.

Because its light is 248 million ly from home, you are seeing NGC 6897 as it looked roughly 248 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.
