Adjustable Solar Filter Metal Film Cover 90-112mm

Safe Solar Observation for Telescopes and Cameras

Observe solar eclipses and sunspots with confidence using this Solar Filter Metal Film Cover. Designed for reliability and consistent optical performance, it blocks harmful solar radiation while allowing a clear, controlled view of the Sun through compatible telescopes or camera lenses. The rigid aluminum alloy frame and high-density solar film work together to deliver stable, repeatable results for both visual observation and photography.

This filter is compatible with optical instruments that have an outer lens housing diameter of approximately 90-112 mm. The integrated clamping screws allow you to finely adjust the fit to your telescope or lens, helping to keep the filter securely in place during use. With an optical aperture of 95 mm and a film density of 5.0 (ND 5.0), it reduces sunlight to a safe level while maintaining good contrast and detail on the solar disc. The metal film is reusable when stored and handled correctly, making it a practical choice for recurring solar events.

Why It's a Smart Choice

• Safe Solar Viewing - ND 5.0 solar film significantly attenuates visible and invisible solar radiation, supporting safe, indirect observation through your instrument when used correctly.
• Adjustable, Secure Fit - Side-mounted screws allow you to tighten or loosen the filter to match 90-112 mm lens housings, helping prevent accidental slippage.
• Durable Aluminum Construction - The aluminum alloy frame protects the film, resists deformation, and offers a stable mounting surface for repeated use.

FAQ

Q: Which instruments is this filter compatible with?
A: It is designed for telescopes or camera lenses with an external front diameter of approximately 90-112 mm. Always measure the outside diameter of your lens housing before ordering.

Q: Can I look directly at the Sun with this filter off the instrument?
A: No. This filter is intended to be mounted securely on a telescope or camera lens. Never look at the Sun with the naked eye or through any optical device without a properly installed, undamaged solar filter.

Q: Is this suitable for both visual use and photography?
A: Yes, the ND 5.0 film is commonly used for visual observation and basic solar photography. Camera settings may need adjustment due to the strong light reduction.

Q: How should I care for the solar film?
A: Avoid touching the film surface, and do not clean it with liquids or abrasives. Store the filter in a dry, dust-free container and inspect it for scratches, pinholes, or damage before each use. Do not use if the film is damaged.
