|
| The C-Ring is re-rigged and lifted off the cradle with the upstairs crane. | It must be tilted to fit through the 10 meter hatch. |
 |
 |
| Up through the hatch it goes. | The C-Ring looks so much smaller upstairs. |
 |
 |
| Clear of the hatch in the observing floor. | Rotate back to the level (45 degrees) orientation. |
 |
 |
| Ready to lower onto the telescope Azimuth Frame. | The Left C-Ring is carefully positioned over the elevation hydrostatic bearing pads. |
 |
|
| The two C-Rings form the precision elevation bearing of the telescope. | |

| The Left C-Ring waits downstairs.... | while the Right C-Ring is on the telescope. |
