Home Built Solar Filter for My Celestron 8″ SCT

I finished building my DIY Solar Filter.

Here are the materials I used to construct my filter.

• Badeer AstroSolar Safety Film – about $35 w/ shipping
• 1 Sheet of Black Poster Board – $0.79 @ Walmart
• 1 Sheet of Black Foam Board – $3.79 @ Walmart
• Black Electrical Tape
• Elmer’s Glue

The total cost of the filter project was less than $45.

I used the directions found here and also here.  The AstroSolar film also came with similar directions.

The Hartman mask template generator gives you a good template to use for where to cut the hole.

Works just as well as the one I bought for my small scope.  I still have some of the Baader AstroSolar Film left so I am going to make a small solar filter for the finder scope.
