The upgrade set includes the secondary spider SW150 and the primary mirror mask SW150 suitable for e.g. Skywatcher 150PDS/QUattro and similar telescopes with an inner tube diameter of 180mm.
Both the spider and the mirror mask are CNC machined and made of aluminum (EN AW 6061). In combination, they improve not only the mechanical stability but also the imaging performance of the telescope by eliminating unwanted diffraction effects caused by misaligned struts or by mirror mounting clamps as well as by sloping edges on mirrors.
Please note! The upgrade set is not compatible to telescopes from TS-Optics!!!
