Good news (and thanks for the puzzle!)

As we said, with real optics, the ability to see the image in the eyepiece is impossible unless you line up the camera.

However, with CG and raytracing, we can invent impossible optics!! Here is a demo.

There are two lenses here: as with a real telescope there is an objective lens and an eyepiece. The objective lens is in the center of this render, and the eyepiece lens is in the right half. The objective lens uses a "real" glass material and has thickness and is biconvex like a real lens. The eyepiece lens is just a single layer of polygons, but curved very slightly convex, and has a special shader on it. (Magic!)

The objective lens is 1.5 inch in diameter. The eyepiece lens is 1 inch. (A modern Poser inch - no arguing about how tall is Vicky please)

The test pawn is far away. In the objective lens it is inverted. The eyepiece inverts again and magnifies!

I will post more as I get closer to a finished piece.

If you have specific dimensions for the scope let me know - the lens distance, size, and curvature are all related and need to be designed together.

Renderosity forum reply notifications are wonky. If I read a follow-up in a thread, but I don't myself reply, then notifications no longer happen AT ALL on that thread. So if I seem to be ignoring a question, that's why. (Updated September 23, 2019)
