Model: bu_sms_sw250Part Number: BU2022-010
CNC milled secondary mirror spider made of aluminium (EN AW-6061), matt black anodised, suitable for Skywatcher 250PDS/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.
What's In The Box
Works well and easy to fit to a 10 carbon Quattro. Not sure how the cost is justified though.
