Being in the same boat for the recent Annular eclipse this past October, I created my own filter for my Tamron 600mm zoom lens. I purchased a 6"x6" solar filter sheet on Amazon from Thousand Oaks Optical for about $10. In addition to the filter sheet I purchased some plexiglass from Home Depot for a few bucks and cut to the match the diameter of my lens. I then cut some 3/8" foam core into a 3" wide strip and length to match the diameter of the lens (in this case 95mm). I backed this strip up with some duct tape and sliced it width wise at 1/4" spacing. I then pressed the plexiglass edge into the foam core 1/2" from the edge to form a groove and seat the plexiglass. Once done I shaped it around my lens and taped the ends together for a snug fit, just tight enough to slip on and off without it being too loose. In the end it costs less than $20 and works great. The photo of the sun was a hand held test photo. Tripod mounted would have made it more in focus and sharper.
Unfortunately, the day of the eclipse was a washout with heavy clouds and rain so I was unable to get a once-in-a-lifetime photo. That said, I might make it to Texas for the Spring '24 eclipse.
I had some wrinkling of the film when I first built the filter because I had cut the film diameter to match the plexiglass diameter. I had to disassemble everything, cut the diameter of the film slightly smaller than the diameter of the plexiglass and reassemble the filter.

Solar film and a needlepoint ring work great for me, been using the same one for about 7 years now. Cost about $16 complete.
