well it’s about time some new telescope designs for space are surfacing…

I like the film-lens concept with the Fresnel lenses.

but I still think my design for ionized gas lenses is easier, better, more stable, and much bigger.

flood a container (a lunar crater will do nicely) with an easily ionized gas, and shape a concave elliptical electrical field to flow through it from surrounding electrodes. The gas will become reflective, and somewhere a picture will form at the focal point.
