Let's rather look at what you have said about the synchronisation
of clocks

The clocks will still be synchronous (within 1 μs).

If the speed of light was infinite, then you would see
the watch in the telescope show 00:00'08" like the watch on your table.
The clocks are synchronous in the ECI frame.

But why do you claim that the speed of light is infinite
when you know it's not?

This is the reality, as you know!
You have correctly explained that you see the watch in the telescope
delayed by 1 second, so you _know_ that the lunar watch shows 00:00'08"
like the watch on your table.
You _know_ the watches are synchronous in the ECI frame.


Of course it is a bad joke that the speed of light is both
finite and infinite, and that you can make a clock change
its reading by looking at it.


You are babbling nonsense.

See? Nonsense!
