Yeah,

I have been doing.

But I'm not getting what you are getting, I'm trying for something like the second image:

And it's just not getting there, this looks like a different model to the telescope, and I'm wondering what you are using as a backing just behind the lens, I've been trying various different materials on a 2d disc positioned just behind the half sphere I'm using as a lens.

So is this just the cut off front end of the telescope?  I can see you've got a pretty low refraction value on the lens.

I've worked at this for a while now, and I can't get any better effect than the second from the right, and I can't seem to get the iridescence that you get.

I think there are just too many factors involved in this that I don't know.
