So I found this lens. I believe it to be a Plat-convex lens (flat on one side) and was wondering of making a telescope.
It's 150mm (~5.9 inch) in diameter and 28mm (~1.1 inch) height.
What other lenses do I need to make a decent telescope to be able to possibly watch and take photos of the moon.

tl;dr Need help for telescope
