NGC 6798
NGC 6798 is a lenticular galaxy in the constellation Cygnus about 114 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 114 million years ago.

Because its light is 114 million ly from home, you are seeing NGC 6798 as it looked roughly 114 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.
