The original mirror was not well made and had terrible astigmatism. But, it did show things that only a large telescope could. M1, M57 M82 and M1 were seen in detail like never before. The telescope was de-commissioned in 2001 as we began the construction of the new 30 inch F6 TROK telescope.

In 2007, we began to think of re-building the old telescope into an ultralight deisgn. This would require the old 1 inc thick plate mirror to be re-ground, polished an figured. We began to make a new grinding machine for this, and also to make three 20 inch F6 plate mirrors.
