Al,
The resolution of diffraction grating depends on number of lines engaged to disperse the light beam of the star under test. More lines in the beam, the better resolution.

With f/10, the distance between SA and focus should be ~200~300mm, so if I place SA inside C11, I can use the same camera adapter and have the optimised spectrum resolution and dispersion
