IC 289 (2013)
This one looks like a piece of jade to me with these colors. The colors are, of course, representative or “false” color, depending on how you want to word that. As an example, here is another rendition of this nebula using almost the same data. For this, the bluer patches indicate slightly stronger OIII emissions while the greener ones are slightly stronger in H-alpha. There are tiny little red things to the left and right of the nebula glowing in NII which look something like slightly smudged stars. I presume they are tiny FLIERS.
North is NOT up. It’s 33.3° clockwise from up.
Hubble data is public domain. I do, however, request that you credit me for the processing of the image if you use it.
