There isn't any telescope good enough to see anything we landed on the moon. From A site debunking the hoax believers:
Earth based telescopes should be able to see the Apollo equipment
A telescope's diffraction limited resolving power depends linearly on the aperture of the telescope. Groundbased telescopes also have to look through the murky and turbulant atmosphere so without corrective techniques that are just now becoming common in large telescopes (called adaptive optics), a telescopes resolution is limited by the atmosphere to about 0.5-1.0 arcseconds (3600 arcseconds are in one degree and 360 degrees around the whole sky). That limits groundbased telescopes to a resolution of about 2 kilometers on the moon. From space, a telescope is limited by its diffraction limited resolution. For the Hubble Space Telescope, that is a little less than 0.05 arcseconds or about 90 meters at the distance of the moon. To resolve the LM descent stage which is about 10 meters across, one would need to have a resolution better than 10 meters, perhaps 2-3 meters which means we need a telescope some 30 times larger than the HST in orbit around the Earth to resolve the largest equipment left on the moon.
