Sextant Sun Filter Modification

A sextant's Sun shade can be replaced or modified by fitting a piece of mylar solar film to the filter frame. Trace around the filter frame onto an index card to create a template that is then used to cut the mylar film to size. Use silicone adhesive applied to shade frame to attach the mylar solar film to the shade frame. The result produces a well filtered sharp Sun with no distortion or refraction.
