Anyone for a new single-lens telescope?

One day perhaps a 10inch scope. Just what I need for my HEQ5.

Yes I saw that article. It has implications for telescopes. Imagine APO performance from a single lens.

Yet to be proven in use of course but exciting prospects. Roland Christen would be very interested in that. He's been a major pioneer and proponent of the APO tripklet.
