Hi Robin,Yes that’s exactly right…Jupiter is an extended object at 550mm focal length so the objective prism set-up blurs the spectrum. One of the methane bands in the spectrum of Jupiter is faintly visible.This was just an experiment to see what is possible with such a system and is reported here to hopefully stimulate interest in spectroscopy in general…Mike.
