The first lens is a, this is the galilean refracting telescope. Other refracting telescopes can be made, itl bit differently. But the first lens was a half concave lens. Convex is when it's like this, right? That's convex. Now, in convex lenses, those converge. The light raywas, and i said concave when i was my eye, oh, im ery, oh, yes.
