You have to be remarkable stupid if you don't understand that
the proper time shown by a clock won't change by being looked at.

OK. Let's start again:

If we ignore the gravitational blue shift, and pretend that
the ECI frame is a true inertial frame, then the lunar clock will
lag 0.45 μs on the Earth clock.
Which we will ignore, as you said we should.
So the clocks are synchronous (within 1 μs).

Considering that transactions are instantaneous,
why do you say that the picture you see in the telescope
is 00:00'07, when it obviously should be 00:00'08" (-0.45 μs)?

Please explain.
