NGC 2830

NGC 2830 is a lenticular galaxy in the constellation Lynx about 284 million ly from Earth. It spans roughly 100,000 ly, about the width of our Milky Way. It is receding from us at about 6,237 km/s.

Because its light is 284 million ly from home, you are seeing NGC 2830 as it looked roughly 284 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.
