About this image

In order to confirm the identity of the target as a planetary nebula additional exposures were taken using a Star Analyser 100. Stars show a continuous spectrum with absorption lines, but a planetary nebula displays bright emission lines. The emission 'lines' of oxygen and hydrogen are indicated here.

Hi Graham,

Nice spectrum!  Looks like there are other blue images near OIII...maybe you've got H beta as well?

Mike.
