| Day's 16.25" F4.5 just returned from the coater with an enhanced coating and silicone overcoat. Nice!! |

| The "mask" is used to place the center "donut" in the center of the mirror. |
 |
| The "donut" in place. This makes for easy collimation. |
 |
| The 18-point flotation mirror cell was built and optimized with Plop. I give the silicone 48-hours to cure. |
 |
| The cell will be "firmly affixed" to the mirror -- yet can be removed if needed. |
