Astronomical Spectroscopy Projects, is certainly a worthy goal, it does not work well for small observatories. Because spectroscopy spreads the light out, taking spectroscopic images of faint objects requires very large telescopes to gather enough photons for a spectrum image. Faint astronomical objects are truly in the realm of the
