Backyard Universe Primary Mirror Mask for Sky-Watcher 200mm Newtonian Telescopes
CNC milled aperture ring made of matt black anodised aluminium (EN AW-6061), suitable for Skywatcher 200p, 200pDS and 8" Quattro telescopes.
This precisely manufactured aperture ring, for mounting on the primary mirror, reliably covers the mirror brackets and the outer area of the primary mirror, thus helping to avoid unwanted diffraction effects caused by the brackets and a sloping mirror edge.
A 2mm chamfer in the inner ring minimises unwanted residual reflections on the primary mirror from the inner edge of the aperture.

I bought this for my Skywatcher 200PDS to improve the diffraction spikes. It comes with comprehensive instructions and was easy to fit. One the primary mirror is removed and the metal mirror clips, the rubber supports are trimmed back before installing the mask. The whole procedure took about 15 minutes and first results on Vega look really impressive.
