We are very sorry to spoil your illusion, but you will be left with the desire. There is no optical instrument with the ability to capture an object so small and so far from the Earth , which is at an average distance of 382,500 kilometers from its satellite.
The American flags planted on the lunar surface in the various missions of the Apollo Program are about 125 centimeters long. Appreciating them from here would require a telescope about 200 meters in diameter. To give you an idea of what that means, just know that the Gran Telescopio Canarias, one of the largest optical observatories in the world, has a primary mirror of only 10.4 meters.
If we know that the flags continue where they left off, it is thanks to missions such as the Lunar Reconnaissance Orbiter probe, launched by NASA in 2009 to explore the satellite, especially its poles.
This spacecraft has photographed the landing sites of the Apollo missions, and has thus shown that almost all the American insignia are still in place, despite the radiation and very low temperatures. There seems to be only one exception: the images have not confirmed that the flag carried there by Apollo 11 in the first manned expedition to the surface of the Moon is maintained.
