Paul; I made two very crude cells, one for the 10 inch Newt and one for the 7 inch Maksutov, both work very nicely and I use those scopes at about 3 inches of aperture for viewing the Sun. I am very pleased with the resolution, color and contrast of sunspots using the Baader film. You can give me the answer at Cherry Rd., what is the date of the partial eclipse?
