Camera Filter Holder

I made an adapter that will hold a filter for solar viewing onto the sun shield of my camera. The back piece, part 1, has a diameter that tapers from 98 to 96.5mm so it fits snugly to the sun shield. This particular one fits the Canon 70-300mm sun shield ET-65B and a 100mm film but you should be able to scale it to fit whatever you need with some trial and error.
