CYCK Integrated Secondary Mirror Spider Telescope Parts for Sky-Wathcer 150mm Newtonian Telescopes
Description:
The secondary mirror spider is ultra thin (only 2.2mm after velveting). Compared to the old version (5mm after velvet), 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 integrated metal spider can effectively improve the strength of the secondary mirror holder, facilitate the calibration of optic axis, effectively improve the rigidity of optical tube of 150mm telescopes, and greatly improve star performance.
Made of aluminum alloy, it is processed by CNC turning. It fits 150mm Newtonian telescopes. The two sides of the secondary mirror spider are designed with chamfered edges, making it look more beautiful and better. CYCK's unique spring grooves are made for big improvement.
Package Included:
- 1 x Set of Secondary Mirror Spider
