IC 4593 (2013)

Finally, I found a planetary nebula that also has some data for the faint halo surrounding it. A lot of planetary nebulas have these but images of them tend to only show the brightest parts while omitting the halo. (Note that’s not a covert criticism, to that particular image. I only linked to it as an example.)

Red: hst_11093_02_wfpc2_f658n_pc_sci
Green: hst_11093_02_wfpc2_f656n_pc_sci
Blue: hst_11093_02_wfpc2_f502n_pc_sci
Halo luminosity: hst_06347_20_wfpc2_f656n_wf_sci

North is up.
