Hi Guys,
Hypergraph's are excellent telescopes but
have a look at this link:

Quote:
Optical performance without equal
The spot size on the plane field of the Hypergraph is more than 20 times smaller compared to a conventional Schmidt-Cassegrain,
about 10 times smaller compared to a classical Cassegrain and
about 8 times smaller compared to a Ritchey-Chretien telescope.
Tight specifications guarantee,
that the theoretical performance is also reached in the manufacturing process.

Could this be business puffery or true?
