About this image

Open in new window to see full size

The relative ratios of dust, C2 and CN etc vary depending on where the spectra is taken. I was hoping to see some sign of the ionised components in the tail spectrum such as the characteristic CO+ doublets seen here in 2020 F3 (NEOWISE) but there was nothing different there apart from perhaps a possible weak unidentified emission line at 4338 A
