you can mount the slides in standard mounts, as the 2 images are shot side by side on a standard 35mm frame. As for a viewer you need a old Stlitz or Pentax slide viewer that views standard 35mm slides. You could also buy a Russian stereo viewer kit - these come with a attachment that lets you use the beamsplitter as a viewer - I've used one with good results before -



PS - I have no connection to the seller- its just the first listing I saw for one..
