@kev596 so you want me to tell you, but won't accept the factual answer?
Well, I'll try anyway, though it's probably too complex for you.
The Apollo lunar module descent stage was about 4 meters across.
The moon is about 380,000,000 meters away, so a ratio of about 1:100,000,000
So using that ratio we can say that the descent stage has about the same angular size as a 1mm flea at a distance of 100,000,000 millimeters ie. 100 km.
You show me a telescope that can resolve a flea at that distance, or the head of a 4mm screw on the ISS from 400km, and I'll show you a telescope that can resolve the LM descent stage from Earth.
