Backyard Universe Upgraded Secondary Mirror Spider for Sky-Watcher 200mm Newtonian Telescopes.

CNC-milled secondary mirror spider made of matt black anodised aluminium (EN AW-6061), suitable for Skywatcher 200p, 200PDS & 8" Quattro. 

This secondary mirror spider is manufactured on a modern CNC machining centre. 

The high-precision manufacturing ensures that the 1.8mm thick struts of the spider are perfectly aligned, and the diffraction-related spikes on bright stars appear razor-sharp. 

The light, stable design, optimised by FEM simulation, also significantly improves the collimation stability of the Newtonian.
