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

This secondary 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 induced spikes on bright stars appear razor sharp. The lightweight, stable design, optimized by FEM simulation, also significantly improves the collimation stability of the 6" Skywatcher Newtonian.
