Filters Double-Stack Filter DSII for Solar telescopes LS80MT & LS100MT

Double-stack module for greater contrast and detail on the sun's surface

The DSII module reduces the half-width to less than 0.5 Angstroms, significantly increasing contrast. This allows filaments, active regions and other surface details to be seen much more clearly.

Please note: The DSII module is only suitable for the solar telescope series mentioned in the product name and cannot be used on other telescopes.

The module is equipped with the Pressure Tuner System for fine adjustment of the etalon.
