Yep, The operational problems caused by moonlight preclude permenant orientation so Analyser not useable which is a pain in the neck.
The following spectrum was derived from an image taken by the Japanese observer Koji Maeda.
I don’t think there can be any more doubt that these spectra reveal there is a particular composition to some Quadrantids. It’s a whole other ball game to consider what might cause the difference (assuming the first spectrum IS of a Quadrantid).
cheers,
Bill.
