I just made a set of filters from the Baader film for my 15x70's. They work great! I took one of the lens caps to Home Depot and looked around until I found a suitable PVC caps to use as the cells. I found some white end caps that fit almost perfectly. I cut down them down to about 1" in length and removed the center of the end to match my aperture. I spray painted the PVC flat black to match my Obies. Then I made a couple of cardboard rings from the backing that came as part of the packaging for the solar film. I smeared a little contact cement on the rings and then dropped them onto the smoothed out film from about 1/2" above. They are pretty wrinkle free. I lined the inside face of the PVC 'cell' with double sided tape and dropped the rings (film side down) into the cells. The one thing I did do was to make sure that the cardboard rings were slightly undersized so that they would drop freely into the PVC cells. This insured that there would be no deformation of the ring/film from a too tight fit.
The sun has been kinda boring lately. Not a whole lot of sunspot activity. We need somebody to come up with cheap h-alpha filters for binocs!!
Good luck!
