I have some Baader Visual AstroSolar Filter material available. 4.1x4.1 sheets are 11.50 shipped. The sheets will be shipped between two 5x8 pieces of posterboard that can be used for a cell, as well as, a pdf file with a more sophisticated cell design. Flyer in pic NOT included.I have other sizes also, please e-mail me with your requirements. PayPal or M.O. are fine.
Thanks and Clear Skies,
