With the Great American Eclipse on Aug 21 only a few weeks away, I decided to put together some solar filters. With the high travel costs to get to the eclipse from Southern California, I saved some money through purchasing the solar filter sheets instead of the pre-made filters. To facilitate a fast detachment during totality, compared to a screw on filter, I made some cardboard holders that fit into my Lee filter holder.
Solar Filter Sheet from Thousand Oaks Optical: $15 vs the $150 Lee solar filter.
Step 1: Get a filter sheet
Step 2: Measure (100mm square) or trace out the shape for the stiff backing material. I used part of an old box.
Step 3: Cut a hole for the filter, for the size I used the filter holder as a template and an knife to make the opening, cutting on scrap cardboard so as to not damage the table.
Step 4: Cut another cardboard sheet for the other side, I used a thinner material so it fit snugly in the Lee filter holder.
Step 5: Tape together
Step 6: Enjoy the eclipse! Remember, never look at the sun without a filter (except during totality). Some other great resources for the upcoming eclipse
