IC 1749
IC 1749 is a lenticular galaxy in the constellation Pisces about 242 million ly from Earth. It spans roughly 75,000 ly, about 75% of our Milky Way's width. It is receding from us at about 5,108 km/s.

Because its light is 242 million ly from home, you are seeing IC 1749 as it looked roughly 242 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.
