Blue Planetary Spectra
Dear All
I aimed my LISA spectrograph at the blue planetary neb in Centaurus. It is a mag8.4 and is 12arcsec across. A good target for the spectrograph.
Using a 24um slit I achieved the spectra below. I have labelled lots of the lines. There is virtually no background spectra. Just emission lines. This demonstrates why narrow band filters work so well with planetary nebs.
