The M48 fitting provides a large clear aperture to reduce halation and a precision thread ensures the triplet and doublet lens groups are precisely aligned on the optical axis perpendicular to the image. 

When used with the field flattener the Esprit-120 ED PRO's imaging circle is 44mm.

After years of R&D we have developed a new solar film that has the optical quality of glass with the advantages of impregnated polymer. Will never develop pinholes or scratches that can let in light and ruin a filter. Other advantages: lightweight and does not require re-balancing tube assembly, will not break, consistent yellow-orange solar image, even density with any aperture, flat surface compared to other thin film filters that have wrinkles and creases. Will not tear or puncture. Stronger than any other solar film on the market. Also available in sheets. Guaranteed 15 years.
