Veil Nebula (4-Panel Mosaic Progress)
Blog Update — Veil Nebula (4-Panel Mosaic Progress)
Over the last few weeks I’ve returned to the Veil Nebula with a proper long-term plan: build out a full 4-panel mosaic with enough integration time to finally pull out the faintest strands of oxygen and sulphur drifting across this ancient supernova remnant.
This new version is my first full process pass using the updated data — now sitting at around 16 hours total exposure spread evenly across the mosaic. Even at this stage, the difference is huge. The extra depth has brought out delicate filaments that were barely visible before, along with more structure in the darker, ghost-like wisps threading through the centre.
What’s been especially rewarding is seeing how the Forax SHO blend responds as the hours stack up. The contrast between the cool OIII arcs and the warm, ember-like SII regions is starting to take on that three-dimensional look the Veil Nebula is famous for.
There’s still more work ahead — more time to collect, more fine-tuning across the panel seams, more experimenting with colour balance and star control — but this feels like a proper milestone. The mosaic is finally beginning to feel complete.
