Continuing with bino atlas project (see thread "A new kind of binocular book..."), we found that it was difficult to visualize and compose images through the camera of the fields seen through BT100 with 24 Pan eps.
Solution: Use 120mm f/5 refractor and mask to 100mm f/6. This dublicates the BTs aperture and f ratio. Using a 24mm Panoptic ep then gives us the same magnification and apparent and real field of view as seen through the binocular(25x @ 2.7 degrees) This is then used as the "finder" for the camera.
