Clio was behaving normally, until tonight. When I aligned the Clio pupil tonight, the pupil wheel motor #2 seemed to be not working somehow. In pupil imaging mode I could tell that the actual pupil stop was 1 position off from what was claimed in the software. The wheel itself is moving fine, so it's possible we lost the home. Anyway, I was still able to align it, by making sure by eye that I had the right cold stop in.

***However, the images have an elongation at L-band that I have never seen before. And it is round on VisAO. So I think this means it is possible one of the other motors is also not homing properly, so perhaps we are going through the camera lens or collimator lens at a steep angle, to make this elongation. What do you think?

Here is the image:

Test on Canopus at dawn on 2015/11/25-26

[3.9] filter, in focus, stamp mode, 43 ms, 20 coadds.

Test1: Left side, Regular Image: -slightly elongated  
  
  
  
  
Test1: Right side, Regular Image: -slightly elongated 
  
  
  
  

Test2: After jogging Motor 3 (Filter Wheel 1) Pretty Far to the Right: 
  
  
  
  
Same one on the Left:

Test3: Moved [3.9] filter back to regular position. Then moved camera lens wheel
  
  
  
  
-Moved star over but did not really change elongation:
  
  
  
  

Test4: Moved the collimator lens just a little. Result: Elongation:

2015/11/26-27 Dawn:
  
  
  
  
Canopus at M-band. Top row left to right: FW1 moved left; FW1 moved right; Normal.
  
  
  
  
Bottom row left to right: Normal; Round by hand/eye; Round - Normal.
  
  
  
  

Pinhole. Left: 3.9um; Right: M-band. 3.9-um FWHM is 98mas while diff-lim is 124mas. M-band FWHM is 120mas while diff-lim is 149mas.
  
  
  
Canopus. Left: 3.9um; Right: M-band. Saturated so I can't measure FWHM.

UPDATE: SOLVED BY T.J.: DO NOT HOME WHEEL 5 CAMERA LENS AFTER ALIGNING PUPIL
