Backyard Universe Secondary Spider SW130
This secondary spider is manufactured on a modern CNC machining center. The high-precision manufacturing ensures that the 1.8 mm thick spider vanes are perfectly aligned and the diffraction-induced spikes on bright stars appear razor-sharp. The lightweight, stable design, optimized by FEM simulation, also significantly improves the collimation stability of the Skywatcher Newtonian.
