An autopsy on the Shack-Hartmann wavefront camera indicated death by power-surge :( Fortunately we have another identical camera (without a lenslet array attached) so Hitesh opened both up, swapped out the damaged card & we're back in business :)
Other progress for the day was the installation of the new cover for the top of the SAC which allows a test mirror to be set up for use with the interferometer.
With that in place, the NRS super-structure could be put back up & the interferometer re-attached so that Francois can play while the rest of us disappear for the weekend...
