CNC machined primary mirror mask made of aluminum (EN AW-6061), black matt anodized, suitable for Skywatcher 130PDS
The precisely machined mirror mask, for installation on the main mirror, effectively covers the mounting clamps* and the outer area of the main mirror, thus helping to avoid unwanted diffraction phenomena caused by the mounting clamps and a sloping edge of the main mirror.
Scope of delivery
- 1 x Primary Mirror Mask, suitable for Skywatcher 130PDS
Please note! The aperture ring is not compatible to telescopes of TS-Optics!!!
*General information:
The mounting is done on the original retaining clips. These may have to be shortened slightly because they overlap the main mirror very far in the original state and can protrude under the aperture ring! The original metal washers on the rubber buffers can be omitted since the aluminum aperture is sufficiently stable.
