There are webcams from Microsoft or Logitech that have a wider sensor, but adapting them to fit a telescope becomes an issue.
The Moon is 30 arcmins wide so you would need a large sensor to cover that area with your 8in scope (almost APS-C size).
Better off getting a camera designed for telescopes, check out this ZWO buyers guide that has heaps of info on FOV of different cameras.
