NGC 5047

NGC 5047 is a lenticular galaxy in the constellation Virgo about 295 million ly from Earth. It spans roughly 250,000 ly, about 2.5 times the width of our Milky Way. The light reaching us tonight left it about 295 million years ago.

Because its light is 295 million ly from home, you are seeing NGC 5047 as it looked roughly 295 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.
