Observing Summary:

Testing the 1.3m image quality after last week's recollimation.
My initial impression is that there are still problems, not
much better nor much worse than before.  One clear effect is that
the out-of-focus images show clear shifts over the sky.  They
are centered in some positions but not in others.  Like something
is loose or flexing.   This will be difficult to figure out.
I'm willing to get some more systematic data on this tonight,
if the CCD controller trouble can be fixed.  It's not working now.
