We removed the window to be on the sky and now go on Neptune for a beammap sequence. !! Acquisition crashed !!

First we do a pointing --> set pointing -5.7 -1.1

Now we check the focus along the Z-axis direction --> set focus -0.5 --> It seems we are seriously out of focus so we do it again with this new correction
