Sky-Watcher Solar Filter (180mm MAK)

Sky-Watcher solar filter 180mm

Observing the Sun is one of the most fascinating disciplines in amateur astronomy - sunspots, photosphere granulation, and planetary transits across the solar disk are breathtaking phenomena you can enjoy even during the day. To make this experience not only beautiful but also completely safe, a proper solar filter is an absolute necessity. The Sky-Watcher solar filter 180mm is designed precisely for this purpose - it protects both your eyes and your optics while delivering a sharp, high-contrast view of our star.

Design and construction

The filter is designed for telescopes with an objective or tube diameter of 180mm. The filter body is constructed to fit securely and firmly onto the front of the telescope tube - with no risk of coming loose even when handling the instrument. The optical element reduces the intensity of solar radiation to a safe level, allowing comfortable visual observation and photography of the Sun without risk of damage to your eyesight or camera sensor. The filter transmits light in the visible spectrum and provides a natural, neutrally toned color rendition of the solar disk, enabling accurate observation and photographic documentation of solar phenomena.

Who is this filter for?

This filter will be appreciated by:

• Beginning astronomers venturing to observe solar activity for the first time
• Experienced observers looking for a reliable, high-quality accessory for their Sky-Watcher telescope
• Astrophotographers - when photographing the Sun, protecting the camera sensor is just as important as protecting your eye

The filter is compatible with refractors, Newtonians, and other telescope types with a matching tube diameter.

How to use the solar filter safely

Safe solar observation with a Sky-Watcher filter is straightforward and convenient. Follow these steps:

1. Place the filter on the front of the telescope before aiming at the Sun - never remove the filter while looking through the eyepiece.
2. Once the filter is secured, focus carefully and observe sunspots, faculae, or other photospheric details.
3. For photographers: attach the filter before connecting your camera, verify it is seated firmly, and only then aim at the Sun.
