Spectrum 4" Full Aperture Film Solar Filter 92-98mm

This premium full aperture polymer film solar filter safely allows solar observation and imaging by blocking 99.999% of the Sun's visible light as an ND 5 filter. The durable 0.002" thick black plastic substrate with absorptive filtering material can be mounted on telescopes, spotting scopes, and camera lenses with 92-98mm outer diameter tubes, and minor wrinkles or warps do not affect the solar image quality. Compatible with numerous telescope models including Celestron 80, Meade DS-70, and Orion ShortTube 80, this full aperture filter maximizes the telescope's usable aperture for detailed white light solar imaging and visual observation.
