Sky-Watcher CYCK Telescope Modification Kit Secondary Mirror Spider DIY Kit for Sky-Watcher 10" 250mm Telescopes

Improvements:
- The secondary mirror spider is ultra thin (only 2.2mm after pasting). Compared to the old version (5mm after pasting), it can reduce obstruction by more than half. It makes stars look better, with fewer broken layers, and the stars are sharper and thinner.
- The shading board is made of aluminum alloy, which is more robust and durable, while eliminating the fan and strengthening the shading effect.
- There is a set of integrated secondary mirror spider with mounting screws. It can greatly improve the overall rigidity and enable stable optical axis and beautiful cross star. A set of primary mirror press ring helps improve star quality. And an aluminum alloy shading plate kit can improve light leakage at the end of the primary mirror.
