Astrozap Filters Off-axis solar filter for outer diameter of 321 to 327mm

These solar filters ensure safe observation of the Sun, offering full aperture (also known as clear aperture) coverage. This design maximizes light intake into your telescope by permitting the complete aperture to be visible. Optimal for daytime viewing under minimal atmospheric disturbance, they include a mask feature for reducing aperture size in turbulent conditions.

Crafted with precision, these premium solar filters feature an aluminum cell securely centered to the telescope tube using nylon thumb screws and felt padding. The clear aperture is meticulously crafted from reflective coated glass, ensuring top-tier durability and quality. Offering a natural yellowish-orange image of the sun, these filters are suitable for both direct viewing and photography.

For added protection and durability, the filter comes in a foam-lined box, offering shock absorption during handling and safe storage when not in use.

This premium solar filter is versatile and safe for photography and direct viewing of the Sun. It can be easily fitted over telescopes, spotting scopes, cameras, or any optical device. The off-center aperture is mounted into an aluminum ring, which slips over the sky end of your optical tube. Secure and center the filter with a nylon thumb screw and felt tab. Proper usage and care instructions ensure a long filter life. When used correctly, it provides a natural yellow-orange image of the sun, revealing solar granulation (Sun's photosphere), sunspots, planet transits, and solar eclipses when present.
