Description

NGC 2174 is an emission nebula in Orion. In my rendition, the blue face contains the star cluster NGC 2175.

I used the follow tri-band expression to create a natural palette for this image:

R: 0.4 * SII + 0.6 * Ha

G: 0.4 * Ha + 0.6 * OIII

B: OIII

I did take some RGB star data, but it didn't add anything to this image, so I did not include it. I used drizzle integration to recapture some resolution (I am slightly under sampled) and then re-sampled the image to about 1.5 x the original sensor dimensions.
