Baader AstroSolar Filter

While the filter is designed for a 200mm aperture, you must verify the outer diameter of your telescope's optical tube. Because telescope tube thicknesses vary by manufacturer, you may need to adjust the fitment to ensure a secure, light-tight seal.

Yes, this filter is engineered for both. It provides a neutral, natural-looking solar image that is safe for the human eye when used with a telescope, and it maintains the high contrast necessary for capturing sharp solar details with a camera.

Baader AstroSolar film is widely regarded for its superior optical quality. Unlike some glass filters that can introduce color casts or internal reflections, this film provides a very flat, neutral image with excellent contrast, making it easier to resolve fine sunspot details.

Always inspect the filter film for pinholes, scratches, or tears before every use by holding it up to a bright light source. If you notice any damage, do not use the filter, as it can no longer guarantee safe solar observation.

You should never look through a finder scope at the sun, even with this filter attached, unless you have a dedicated solar filter specifically sized for that finder scope. It is safer to cap or remove your finder scope entirely during solar observation to prevent accidental viewing.
