Description:
The primary mirrors of all Star-Watcher series of Newtonian reflection telescopes all use parabolic primary mirrors with sharp central image quality, which improves the problem of hypertrophy of the spherical mirror edge image quality and ensures that they have sharper and more delicate image quality. The mirrors of this series are all coated with aluminum dielectric and protected with a silicon oxide coating to ensure durability! This series of parabolic mirror reflectors and all DOB models use a four-arm central secondary mirror support (0.5 mm thick) to reduce diffraction peaks and light loss.
