I completed the prototypes over the weekend; they look and perform well. I also have parts for 4 more sets. I was going to put these on eBay, but will sell them at a fixed price for list members. Baader filter material, PVC construction. Made to fit the Apogee 20x80mm binoculars, but if you remove the felt liner they will fit up to a 3-7/8" OD tube or dewcap. Also, the filter material is replaceable, should it ever require changing- you don't have to throw the cell away when the filter needs replacing. Price for list members: $50/set (thats 2 filters, folks) Deilivery will be in approximately 3-4 weeks (waiting for more Baader material). Contact me off-list if interested. Any sets not sold by the end of March will go to eBay. Thanks Chuck __________________________________________________ Do you Yahoo!? Yahoo!
