Thank you, Bruno. The workflow you suggested makes an enormous difference getting the images to appear in the correct relation to each other in the preview modes, and I can replicate your optimization values if I use that workflow on my original PTO. Unfortunately, your PTO (fixed) results in a great stitch, while mine inexplicably results in only a narrow horizontal band of the mosaic along its 'equator' appearing correctly exposed in the preview. The rest of the images are very dim. This band is also the only bit that gets stitched into the final image. I've used the Move/Drag tab's 'Fit' and 'Center' buttons, along with the Stitcher tab buttons to calculate 'field of view' and 'optimal size', and also tried adjusting the preview sliders, but nothing changes this band. I've attached my PTO again, but it looks almost identical to yours. Please advise if any other information or screen shots might be useful.
Despite the persistent problems I really appreciate the help with the workflow. Hopefully, others read this thread and have success with their own projects.
