Looks great. Similar ideas to many of the newer ATM scopes out there at the moment. I'm interested that he managed to eliminate the bump where the bearing folds over. In the Tridob design I copied for my 16" scope this is accomplished by having three fins, with the front two folding over the mirror box, but it requires extra bits of teflon as keepers on the sides.,324,0,0,1,0

Can't see the point of the shroud to be honest, as most stray light gets in around the top end around the focuser and secondary assembly, and this is above the shroud in this design. Also, light is not blocked from getting into the light path around the primary either. Might be more to do with customer perceptions than blocking stray light. personally, I'd be baffling the focuser and using a bigger baffle behind the secondary instead.
