I was interested in your stratedgy of fitting a curved spider for the tertiary mirror rather than the more traditional approach of using another 4 vane spider and adjusting their position optically to line up with the secondary 4 vane spider .
Well I am still experimenting with the veins.

I want to stay away from having the four veins aligned with the secondary because it is hard to do it precise and if it is off by a fraction the defraction spikes on a star image will be quiet long.

There are still other options to try. The thing in desinging and biulding your own scope is that if something dosen't work.... well, you find something that does.
