Updates on the f/8 recovery are now in inverse chronological order.
2013.7.23
The mirror has been successfully coated (on July 11th) and is now waiting to be installed in the assembly for its return to the telescope next month.
The photo below shows the coating crew examining the mirror in the tank after coating.

The engineering run has now completed. The secondary assembly was successfully installed, aligned and removed. Improvements in handling procedures and modifications to the handling equipment were identified, and these should largely be implemented before the next run (second half of August). In addition, the secondary actuator and vacuum systems were exercised and re-work tasks were identified.
The picture below shows the top end of the telescope re-configured for DECam operation; the red counterweight assembly at the bottom of the cage in past pictures is now black and about 100 kg lighter.
