Selection of interesting planetary nebula (PN) spectra
Mouse over name to view preview, Click on name to goto page.| A "standard" PN spectrum showing the common peaks from hydrogen, oxygen and nitrogen. | |
|
PN showing no oxygen | |
|
PN showing no nitrogen | |
|
Protoplanetary nebula (PPN) shows only hydrogen | |
|
The Spirograph nebula. Shows rarer lines from the main elements as well as lines from helium, sulphur and argon. | |
|
Spectra from Nebula and central star separated. The central star shows a spectrum of a white dwarf with absorption lines from residual surface hydrogen. | |
|
Spectra from Nebula and central star separated. The central star shows an emission spectrum similar to a massive, hot, carbon-rich Wolf-Rayet star. | |
|
Raw spectrum showing light pollution in image. Light pollution lines show up vertically across the whole spectroscope field of view. Spectra show raw image and with light pollution subtracted to show spectrum of object. |
