Carbon Fibre Tube suitable for Skywatcher 130/650 PDS. Carbon fibre composites, also called carbon or CFC, have extreme strength & stiffness, low density and unique design.
Backyard Universe carbon fibre tube upgrade for the Skywatcher Quattro 150mm Telescopes. Extremely strong and lightweight. A useful upgrade for these telescopes.
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
The secondary mirror cover can be used to cover the rear side of the secondary mirror. This considerably reduces the cooling of the secondary mirror through radiation exchange with the upper atmosphere which reduces the risk of dew condensation.
This secondary spider is manufactured on a modern CNC machining center. The high precision manufacturing ensures that the 1.8mm thick struts of the spider are perfectly aligned and the diffraction induced spikes on bright stars appear razor sharp.
