ATM R-vV planetary scope

[eedbrcu@eede.ericsson.se (Bratislav Curcic)]

Has anyone ever heard about what happened to the prototype
of the planetary telescope designed by Rutten and van Venrooij
in some of the old TM ? They mentioned that someone in Holland (?)
was making a 10" prototype, but I've never heard about what happened
to it later. To clear things: this was a high performance scope
based on a fast spherical mirror and 3 element corrector (ordinary 
glass) that would increase final f-ratio to something like f/20, 
and at the same time keeping the obstruction below 10%. Has anyone
else built it ?
