IC 289
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.
Red: hst_11956_04_wfpc2_f658n_wf_sci
Green: hst_11956_04_wfpc2_f656n_wf_sci
Blue: hst_11956_04_wfpc2_f502n_wf_sci
North is NOT up. It's 33.3° clockwise from up.
