during the process of startup the bcu2k didn't come up a second try of operate was complete. The masterdiagnotic process didn't restarted and it can be seeing in the ocam not live. A restrart of the masterdiagnostic requires a power cycle of the bcu2k and set the bin again recovered the ocam

Test preset.

record time to center the camera lens.?

how much time is converging...??

the camera lens didn;t move correctly.. what is it happening.

moving manually the camera lens and processes finish. CL posiiton:x=31.10,y=20.3 @341.

pull out the star..

with the star out of the hot spot and illuminating one pupil....
