6-point flotation mirror cell installed on mirror board (Since this is light mirror, a Baltic birch/aluminium cell works well) |
Progress continues on John T's 13.1" telescope with a Coulter mirror. The mirror and secondary has a 96% enhanced coating -- brand new. This is going to make a nice telescope!!
The mirror cell and mirror board from the rear. |
Silicone has been applied to the 6-point cell. The center rear of the mirror is marked with a "donut". |
Once the mirror cell has been applied to the mirror the silicone needs 24-hours to cure. You can see the 3.1" secondary to the lft. |
