Solar Filter for Sky-Watcher 120mm Refractor Telescopes
This specialized solar filter is designed exclusively for Sky-Watcher refractor telescopes with a 120mm main lens diameter. The filter is manufactured from high-quality materials that safely reduce solar radiation intensity to safe levels for observation. Thanks to precise manufacturing, it ensures even light distribution across the entire objective surface and minimizes the risk of damage to optics or observer's eyesight.
Safe Solar Observation Capabilities
Using a solar filter enables fascinating observation of various solar phenomena in a safe environment. You can observe sunspots, their development and movement across the Sun's surface, watch solar granulation, or capture rare events such as solar flares. Solar observation with a quality filter opens an entirely new dimension of astronomy that can be practiced during daylight hours and offers a constantly changing spectrum of interesting phenomena.
Compatible Sky-Watcher Telescope Models
This filter is designed specifically for Sky-Watcher telescope models with 120mm objective diameter, including:
- Sky-Watcher Evostar 120mm refractors
- Sky-Watcher Explorer 120mm series
- Sky-Watcher Startravel 120mm models
- Other Sky-Watcher 120mm aperture refractor telescopes
Installation and Safety Guidelines
Before each use, it is essential to check the filter's integrity and proper attachment to the telescope. The filter installs on the front of the telescope tube and must be securely fastened to prevent loosening during observation. Never look directly at the Sun without a filter, nor use it to search for the Sun through the telescope's finder scope. To locate the Sun, use the telescope's shadow method or orient yourself by the shadow cast by the tube on the ground.
Maintenance and Storage
Solar filters require careful handling and proper storage. After use, clean the filter with a soft cloth and store it in a protective case in a dry place away from direct sunlight. Regularly inspect the filter's condition - even the smallest damage such as cracks, holes, or scratches can cause serious eye injury. A quality solar filter when used properly provides years of safe observation and allows you to discover the beauty of our nearest star.
