I am planning to use my new C11 for spectroscopy...
The idea is to use existing GRISM
I already used it with MTO_10_1100A, but because I could not go deeper into tube (field element was in the way), the light cone at SA was ~5mm in diameter, so the resolution was not great.
Now, I can go deeper inside the baffle (150~200mm away from camera sensor), to fully utilize the resolution of Star Analyser (calculator is here:

There will be a lot of 3D printing and turning plastic tubes on lathe...
