Solar Projector…..The Eclipse is coming!

My solar projector is the best on the market today bar none and there is no better way to view the sun for the coming eclipse.  I have a limited number of solar projectors in stock so get yours before they sell out!  See it in my yard sale or in my You Tube video:

6 inch F/8 Chief

Well that stinks, the 325 mm focal length lens was dropped from the available lens catalog so you can’t make the design I had posted here unless you make the lens.  However there is one more 6 inch design that uses commercial lenses and hopefully they will still be available.  I uses 220  and -250 mm lenses giving a little bit shorter BFL, a final F ratio of F/7.6 and a Strehl of .993.
