Using Einstein's synchronization checking procedure :

at t_A = 00:00:08 send a light beam to the clock on the Moon.

It will record t_B = 00:00:09 at reception time and send you back
another light beam

You will record t'_A = 00:00:10 at reception time

t_B - t_A = 00:00:01
t'_A - t_B = 00:00:01

same values.

By *definition* both clocks are synchronized.

So what was the time of the event corresponding to the image
you've seen on your telescope "00:00:07" ? It was, according
to everyone at rest in your frame when your clock was showing
00:00:08, one second in the past.

And guess what ? 8 - 1 = 7 ! Hooora!

Another question, doc?
