Thanks for info.
Did you also read the thread about the new Maxvision 5" air spaced triplet APO.
They compared it (very favourably) to a 7" TMB APO !
Not conclusive (by any means) but we're talking about a cheaper Chinese scope now being compared in the same class as Tak130's, FSQ106's, TMB 5 to 7" AstroPhysics EDT130 etc
