## Long description

The Beta Baader ND 3.8 Solar Filter 20x29cm is an essential accessory designed for safe solar observation and astrophotography. Measuring 20x29cm, this neutral density filter effectively reduces sunlight intensity to optimal levels specifically for specialized imaging equipment. It provides reliable performance for astronomers during various solar events.
Advantages
This solar filter offers precise neutral density attenuation tailored specifically for imaging gear, ensuring that light transmission is controlled accurately. The generous 20x29cm size provides flexibility for custom setups and installations. Manufactured to high optical standards, it supports high-contrast capture of solar details without introducing unwanted optical distortions, making it a dependable choice for dedicated astrophotographers.
Suitable for
Specialized solar astrophotography with digital cameras or dedicated planetary cameras
Custom filter cell construction for various telescope apertures and telephoto lenses
Capturing high-resolution images of solar surface features and sunspots
When it may not be suitable
This filter is strictly designed for photographic and imaging purposes with specialized equipment and is not suitable for visual observation through eyepieces, as the transmission level is too high for the naked eye. It should also be avoided by users who require a pre-mounted visual filter rather than a sheet format that demands custom adaptation.
Key specifications
Filter type: Neutral Density (ND 3.8) Solar Filter
Dimensions: 20x29cm
Application: Solar astrophotography and specialized imaging
How to use
Before use, inspect the filter sheet carefully for any pinholes, scratches, or damage. Construct a secure, custom-fit mounting cell to attach the filter material firmly over the front aperture of your telescope or camera lens, ensuring it cannot be dislodged by wind or accidental contact. Always ensure the filter is positioned securely before directing any optical equipment toward the sun.
What to consider before purchase
Verify that your intended application is strictly photographic, as ND 3.8 is not rated for visual use
Ensure you have the technical capability and materials required to build a safe, secure mounting cell for the 20x29cm sheet
Confirm the dimensions match or exceed the clear aperture of your optical instrument
Always double-check the secure attachment of the filter cell before every observation session and never attempt visual viewing through an ND 3.8 filter.
