Summary

This part allows you to use basic laser with your Skywatcher 6x30 finder. You can use a standard O-ring (inside diameter : 28 / section : 3.5) to ensure a perfect fit.

You can use the original screws to ajust the sight as usual !

If the laser tightening is not sufficient, you can add a little 2mm screww to tighten the laser (but it it not mandatory).
