I'm new to bird watching and I recently picked up an old Kowa TS-611 with a, I think, TSE-Z6 20-40x 60mm zoom eyepiece. Does anyone know how I can adapt this to take photos with a Canon 5DmkIII, and also an iPhone 8? Kowa's website offers suggestions - for the iPhone the TSN-AR66Z (50mm)? and TSN-IP8 RP? But I can find nothing for the Canon. Any help would be much appreciated. I picked it both the scope and eyepiece for £120. Was this a good price? Many thanks!
