Not visible for a few days yet from the observatory so I rigged up a portable setup last night using a Star Analyser in front of a 50mm lens on an AS120mm camera, normally used as a guide camera on the ALPY spectrograph.
There is not much contrast between the spectrum and the bright sky but the sodium emission is clear.
Cheers
