CHANGELOG

v1.6

  • Minor compatibility updates for PixInsight 1.9.4 transition
  • Conservative JavaScript syntax cleanup.
  • Improved null-view and temporary-window checks.
  • Added safer adaptive-combination guards.
  • Fixed camera sensor selector update for SH/Hβ coefficients.
  • This version is not V8-native and does not solve macOS ARM64 legacy runtime limitations.

v1.5

  • Improved OIII extraction pipeline
  • Band-specific background offset removal
  • HBeta extraction added
  • SII combination for SO and SH filters added
  • Improved OIII combination for HO and SO filters

v1.4

  • Improved OIII extraction
  • Added physical correction factor to avoid over-subtraction of R in G/B channels.
  • Greatly reduces black clipping in low-OIII regions while keeping physical consistency.
