Sure, the delay is known.

But how would you remove it?

The difference in time is actually HUGE, hence you would need to wait a 
VERY long time, if you want to know the present position of stars seen a 
few billion light years away.

In the meantime cosmologists explain the positions of stars, which do 
not belong to the same time.
