Aperture ring SW130, CNC-milled by Backyard-Universe

Description

CNC milled aperture ring made of aluminum (EN AW-6061), matt black anodized, suitable for Skywatcher 130PDS

The precisely manufactured aperture ring, for mounting on the main mirror, reliably covers the mirror brackets* and the outer area of ​​the main mirror, thus helping to avoid unwanted diffraction effects caused by the brackets and a sloping edge of the main mirror.

scope of delivery

• 1 x aperture ring suitable for Skywatcher 130PDS

*General remark :

The assembly takes place on the original holding rubbers. These may have to be shortened a bit because in their original state they overlap the main mirror very far and can protrude under the aperture ring! The original sheet metal discs on the rubber buffers can be omitted because the aluminum cover is sufficiently stable.

Please note! The aperture ring is not compatible with TS-Optics telescopes!!!
