Details:
After taking countless "normal" photos of comet Neowise I decided to give it a quick go at a spectrum. Promptly the coma shows emission lines (C2, CN), which explain the greenish colour. Naturally the dust tail produces a continuum spectrum. Canon EOS 5D3, Canon 100-400mm @ 400mm, f5.6, 6400 ASA, 30sec, flint prism.
