I've got almost a full yard of Baader filter material on hand, so if anyone needs either replacement filter mylar only, or a complete filter with cell, contact me. I have molds for many large-diameter cells already on-hand and can make fiberglass cells for your telescope, or if it's a small aperture (under 5") I can turn a PVC cell on my mini-lathe or make one with the router. Pricing on the cell depends on aperture and whether I already have a mold for that diameter or need to make one from scratch. I'll sell you filter material at cost if you just need to replace the mylar in an existing cell or want to make your own. Note that you get a square piece, not round, and pay for the unuseable corners, but that's life. Sometimes the corner remnants are large enough to make a filter for your finderscope, or a viewer for unaided-eye partial eclipse watching. I can also make pairs for binoculars; I use a pair for my own 15x70mm and 20x70mm binos. Contact me privately if interested.
