IC 1688
IC 1688 is an elliptical galaxy in the constellation Pisces about 236 million ly from Earth. It spans roughly 26,000 ly, about 26% of our Milky Way's width. The light reaching us tonight left it about 236 million years ago.

Because its light is 236 million ly from home, you are seeing IC 1688 as it looked roughly 236 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.
