Glad this target's quite popular this season, its a beaut!
Played around with a couple of different colour blendings, but ended up just going with 'ole faithful' cause I think it highlights the contrast differences slightly better.
The narrowband channels PIP'd together, synthetic lum from the nb as well; then some rgb stars screened in. ~22 hrs nb and ~1 hr rgb. Esprit 120/294mm/eq6r.
