Gabriela Mistral nebula
Gabriela Mistral nebula. Red: SII 8 hrs. Green: H-alpha 4.5 hrs. Blue: OIII 10 hrs.
FLI PL16803 and 3nM Astrodon filters on 20 inch PlaneWave CDK.
SII emission indicates dredged-up material from deep within stars. There are two areas of strong SII emisson here.
(1) Towards far right, Gabriela Mistral's "face" is outlined in a very thin but bright and clear SII shock front.
(2) Towards far left, behind Gabriela's hair, is a much more diffuse but ropy mess of shock fronts in a clear bright semi-circle. This is presumably a supernova remnant.
