Description

This planetary nebula is extremely large and extremely dim.

Yet it shows quite an intricate geometry of bands and filaments where OIII, HA and SII emissions dominate.

I used a fairly conventional SHO palette and kept green intact to showcase the richness of structure.

Collecting enough signal allowed me to use a synthetic SHO signal for luminance rather than HA-only luminance.

Still, since the dim regions have no sharp boundaries whatsoever I preferred to keep the background sky levels elevated rather than cutting off low level information.

Let me know what you think.
