They do indeed look very interesting:

That said, looking at the Zygo data, something doesn't add up. The airy pattern and point spread is slightly but very clearly astigmatic....yet they are claiming a Strehl of 0.98??? Who wrote this report? Trump's speech writer?

I'd send my Taka FSQ106 back if it had similar astigmatism.

That said, the mechanical design and inclusions look very seductive. I could be tempted to try one out of sheer curiosity. Assuming you get a copy with
no optical vices...gee...I'd agree it would be had to justify the $14k or so for a Taka FSQ.
