Sky-Watcher 200/1000 Primary Mirror
The high-quality parabolic primary mirror Sky-Watcher with a 200mm diameter and 1000mm focal length represents the heart of every Newtonian telescope. This precisely ground mirror is the key optical component that determines the quality of observing and photographing the night sky.
Precise Optical Parameters
The mirror has a diameter of 200mm (8 inches) and a focal length of 1000mm, corresponding to a focal ratio of f/5. This ratio is considered an optimal compromise between image brightness and detailed resolution, making the Sky-Watcher 200/1000 mirror suitable for both visual observation and astrophotography.
Parabolic Shape for Perfect Imaging
Unlike cheaper spherical mirrors, this mirror features a precise parabolic surface that eliminates spherical aberration. This provides sharp imaging right to the edges of the field of view, which is essential for observing planets, the Moon, and deep-sky objects.
Highly Reflective Coating
The mirror surface is equipped with a high-quality aluminum layer with a protective SiO2 coating, ensuring high reflectivity (typically above 88%) and long service life. This treatment protects the sensitive mirror surface from oxidation and mechanical damage.
Application and Compatibility
The primary mirror is designed as a replacement part or for upgrading existing Sky-Watcher Newtonian telescopes with a 200mm tube diameter. It can also be used when building your own telescope or renovating older instruments. The mirror is supplied with a holder and adjustment screws for precise collimation of the optical axis.
Care and Maintenance
The mirror should be protected from dust and moisture. If necessary, the surface can be carefully cleaned with specialized products for astronomical mirrors. Regular collimation checks ensure optimal optical performance of the telescope.
