      Load the images, eventually correct Field of View, On Image paramters
      tab (eventually choose "Advanced" interface) in the Yaw column
      manually set second image to 180°, spot preview in pano editor
      (Ctrl+E). If necessary you can try to find some control points in the
      overlap and get an even better alignment. Save the project for later
      use as a template.

      For better results you might want to calibrate your lens. This is
      best done with a 3 shot or 4 shot panorama where you can use the
      control point generator, generate lots of control points and optimize
      for FoV, a, b and c and eventually lens shift (in case of a slightly
      decentered FC adaptor).

      best regards
