Paul,
Indeed spectroscopy appears to be a growing and expanding area. It is something I would like to do. At the moment I’m not in a position to do so, but would like to learn. As far as I’m aware there are no remote rental facilities which could be used.
I’ve just acquired a rather nice 0.5m F:5 Newtonian reflector with Surrier truss OTA which I will erect next spring/summer and I would like to dedicate some imaging time to spectroscopy.
