There is a lot to see even in very small Telescopes and even Binoculars will show some detail. There are Craters Mountains and shadows that are cast by these objects. You will see the landing sites of the US and USSR moon programs , but you will not see the landers themselves. Avoid looking at the moon when full as the features will be bleed out. Try looking for the Libration of the moon.
Libration is a wobble that allows varying amounts of the lunar surface to be seen.
Go to Solar web page Planetary Planetary astronomy is one of my favourite types of astronomy and was the most popular many years ago. You will need a good tripod and a good night for some of those things to be seen. To see any features you will need a Telescope. Mars shows markings and polar caps but can be small and there is only a short time to observe mars. But it does have a lot to offer.
