Backyard Universe Upgraded Secondary Mirror Spider for Sky-Watcher 130mm Newtonian Telescopes.
CNC milled secondary mirror spider made of matt black anodised aluminium (EN AW-6061), suitable for Skywatcher 130PDS.
This secondary mirror spider is manufactured on a modern CNC machining centre.
The high-precision manufacturing ensures 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 considerably improves the Skywatcher Newtonian's collimation stability.
