How to Make a Solar Eclipse Lens Filter for $15 Instead of Paying $150+

With the Great American Eclipse on August 21, 2017, only 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 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 a 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 fits snugly in the Lee filter holder.

Step 5: Tape together.

Step 6: Enjoy the eclipse!

Here are some examples of solar eclipse photos I’ve shot:

2012 Partial Eclipse of the Eastern Sierra’s.
