Stack, flatten, calibrate and restore in SyQon Studio, or drive the same neural models from PixInsight. DeepPrism runs in two passes: Advanced while the data is linear, Ultra once it is stretched.
SyQon Studio: Raw Frames to Finished Image (OSC)
My end to end SyQon Studio path for colour camera data: organise and stack in Fusion Stack, solve and flatten while linear, calibrate colour against Gaia, restore, then stretch stars and background separately and finish on layers.
The Core PixInsight Workflow (OSC)
Flatten, calibrate, correct, separate, denoise, stretch, recombine. The fixed order I run on every one-shot-colour stack before any creative work starts.
Astro Color Mixer: Targeted Colour Control
Band shaping, Range Mask targeting, probe feedback and the pass system in PixInsight. My working reference for the second half of the tool, where the sliders stop being global and start being surgical.
