| This full aperture solar filter fits the Takahashi FS-102, TSA-102, FSQ-106, and FSQ-106ED (New Q) refractors. It has a 127mm (5”) clear aperture Type 2+ glass filter element. The filter element is mounted in an aluminum cell with a 146mm (5.75”) internal diameter. This allows it to fit scopes with a maximum outer diameter of 144mm, using three to four tabs of the supplied self-adhesive thin felt on the inner rim of the cell to provide a snug and rattle-free fit. The filter comes with two long strips of felt for mounting, each 3/4” wide. One strip measures 1.1mm thick, while the second is 2.2mm thick. You can custom-fit the filter to other telescope tubes down to a 137mm o.d. by using two layers of the 2.2mm thick self-adhesive felt on each of the tabs. Always remember to install the solar filter before pointing your telescope at the Sun to avoid instant and irreversible damage to your eyesight. |
