Secondary mirror spider SW150, CNC-milled by Backyard-Universe

Description

CNC milled secondary mirror spider made of aluminum (EN AW-6061), matt black anodized, suitable for Skywatcher 150 P/PDS/Quattro

This secondary mirror spider is manufactured on a modern CNC machining center. 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 collimation stability of the 6" Newtonian is also significantly improved thanks to the light, stable design optimized by FEM simulation.
