IC 5250B

IC 5250B is a lenticular galaxy in the constellation Tucana about 150 million ly from Earth. It spans roughly 76,000 ly, about 76% of our Milky Way's width. The light reaching us tonight left it about 150 million years ago.

Because its light is 150 million ly from home, you are seeing IC 5250B as it looked roughly 150 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.
