Hi Frank,

Congratulations. Great effort. You will be feeling good after all your hard work, and perseverance having borne fruit. There is something special about the view through a scope, when the scope, and mirror has been forged from ones own personal vision, and effort.

I am still working on getting my 25" mirror to work in my dob. Still having edge support bothers. I can put the mirror into the cell and have "stig",(star images as streaks, which change orientation when moving through focus), take it out and put it in again and "no stig", (star images point like, and inter/extra focal images similar). Put it (mirror) in again last evening for optical testing in scope, some stig is back, but still did a good job of separating the a1/a2 (4sec arc),components of Alpha Crucis with plenty of dark sky between. In fact a much clearer separation than the 14" dob gave set up beside. The 25 is yet to be coated, this I intend to do myself *silvered*, when I get the edge support issue sorted.
