📷 ND Filter Holders — safe solar flux attenuation

When observing the Sun with Sol’Ex, it is essential to reduce the incoming solar flux to protect the entrance slit and improve observation comfort. Neutral Density (ND) photographic filters (HOYA, B+W, etc.) are widely used for this purpose.

Our accessory is a dedicated 3D-printed holder, fitted with an aluminium threaded ring to mount standard ND filters (62, 67, 77, 82 mm and more). It adapts directly to the dew shield of your telescope or photographic lens.

⚠️ Please note: the filters themselves are not included. You only receive the mechanical holder, designed to host your own ND filter.

For more details on the principle of using ND filters with Sol’Ex, you may consult Christian Buil’s dedicated article (Part 6).

⚠️ Never point your instrument at the Sun without appropriate filters and protection. Incorrect use may cause permanent eye injury or damage to your equipment.
