Default Light Years and telescope question

If the Hubble is looking at a galaxy 50 million light years away are we
seeing the light just reaching us now (from 50 million light years ago)?
Or is the time span reduced since we are viewing it through a powerful
telescope, in other words compressing the time span for the light to reach
us.

Thanks for any help.

We are seeing the light from 50 million years ago, a telescope doesn't do
anything to shorten that time.

The Year is 2003, the place is Rosamond,Ca., the Telescope name is Babylon 8
