Have changed lens and set focal length to ~300mm. Added extension bar above pegboard. "updated' python program in steps 12, 13 above did not work. The earlier version seemed to run (note it hangs in open loop, on purpose).
Tried power cycling the camera and plugging and unplugging but still getting "camera not found" gphoto2 errors.
Fixed cable issue and got connected to camera. adjusted zoom, focus, and pointing to get to:
The metal bars hold 7 fibers each.
In order to get a good focus I set lens to autofocus (AF), and increased exposure time to 1/10 sec or so. Did partial-button-push to engage autofocus, took and image. Then I switched the lens to manual focus (MF).
Plan for tomorrow:
- find DC light source and use it to focus
try different fiber couplers
replace batteries
