I think I may have said this elsewhere, but IMO the type of glass is irrelevant if the scope does the job as advertised. The figure of the glass elements is at least as important. If the scope exceeds expectations, that's a bonus.
The obsession with labels and "prestige" over the pond leads to this kind of non-sensical thinking, or lack thereof.
I'm sure sticking a camera on the back will be illuminating
(sorry, couldn't resist the pun). The most common issue with doublets seems to be blue halos, but at f/8 I'd be surprised if this was an issue with this scope.
FWIW, I've made no secret that I would like one of these myself, one day
