Yeah, I looked it up on Boz's site and not only are there no front filter threads (which I knew), but the outside diameter of the permanent hood is 127mm (5"). This is a size that I've found NO ONE makes in slip-on filters for telescopes, so my only option is to buy a sheet of mylar solar filter material. Fortunately, I've found a telescope shop over in San Francisco that has it in stock, so I think I'll be able to just tape a sheet over the front of my lens, or maybe make some sort of cardboard holder for it so I don't get light creeping in from the sides. Thanks, everyone, for the tips and suggestions. Turns out there's a lot to know when it comes to photographing our closest star!
