I'm making good progress on a 16" F4.5 truss telescope for Andrew in Encino. It's a rebuild of a Meade Lightbridge. I'm using the Meade mirror and mirror cell, secondary and spider and focuser.  One interesting feature of this truss telescope is the "single top ring". It makes for a light but very sturdy assembly. There is no NO flex what-so-ever and the laser collimator "dot" stays right in the middle of the mirror
