Re-making+the+30+inch+F4+TRO+mirror

The old TRO 30 inch mirror is 1 inch plate galss. The original mirror was very poor quality optically, but it still showed us objects in the sky like never before!

The original mirror was made during 1997 and was completed for first light in 1998. It was de-commissioned around 2001. After this we began to make the new TROK mirror.

In 2007 we had the idea of re-making the mirror. If it we could make it 'good' for low power, then it may be possible to make a 1M (40inch) mirror out of 1 inch plate glass.

We would need to grind the back of the mirror flat (which was never done) and then re-grind the front, polish, figure and test. The pages below detail this.
