Actually you can, just find public access telescopes like at museums etc. Most people don't question again after they see it. hehe
Can you see the flag or other objects left behind on the moon from the Apollo missions?
Unfortunately the answer to this question is no. Not even the most powerful telescopes ever made are able to see these objects. The flag on the moon is 125cm (4 feet) long. You would require a telescope around 200 meters in diameter to see it. The largest telescope now is the Keck Telescope in Hawaii at 10meters in diameter. Even the Hubble Space telescope is only 2.4 meters in diameter. Resolving the lunar rover, which is 3.1 meters in length, would require a telescope 75 meters in diameter. So our backyard 6 inch and 8 inch telescopes are not even going to come close!

Is the flag that the astronauts left still on the moon? If so can it be seen by using a telescope? What about the lunar rover? Can we use the Hubble Space Telescope to see anything left behind by the astronauts?
Yes, the flag is still on the moon, but you can't see it using a telescope. I found some statistics on the size of lunar equipment in a Press Kit for the Apollo 16 mission. The flag is 125 cm (4 feet) long, and you would need an optical wavelength telescope around 200 meters (~650 feet) in diameter to see it. The largest optical wavelength telescope that we have now is the Keck Telscope in Hawaii which is 10 meters in diameter. The Hubble Space Telescope is only 2.4 meters in diameter - much too small!
Resolving the larger lunar rover (which has a length of 3.1 meters) would still require a telescope 75 meters in diameter.
Even barely resolving the lunar lander base, which is 9.5 meters across (including landing gear), would require a telescope about 25 meters across. And in reality you would want a couple (or a few) resolution elements across the object so that it's possible to identify it. (Otherwise it'll look like a one pixel detection, not an image, and I don't think people would be convinced by a couple pixels!) In addition, with a ground based telescope, you have to deal with distortion by the atmosphere as well, so you'll probably want something considerably larger than 25 meters if you want a good, believable, image of the lander. We don't have anything that big built yet! So there's really no way to image equipment left behind by the astronauts with current telescope technology.
