Because raw data is "linear," it looks nearly black to the human eye.
PixInsight calculates a separate, independent stretch for each channel. This effectively "neutralizes" the background by aligning the histograms of the individual colors. Why Linear Images Need "Unlinking" Initially
Once the image is color-calibrated, you must Link the Channels . A Linked STF will now show the "true" balanced colors you just created. If you keep it unlinked after calibration, the STF will override your calibration and show an artificial color balance. Pro Tips for Managing the Link pixinsight lerar link
PixInsight applies the same mathematical stretch to all three color channels (Red, Green, and Blue) based on the image's overall statistics.
Standard processing in PixInsight follows a specific path regarding the STF link: Because raw data is "linear," it looks nearly
Raw astronomical data often has a heavy color bias, frequently appearing green due to the Bayer pattern of color cameras or atmospheric conditions.
When you use an Unlinked STF (Ctrl + Click the "Radioactive" icon), PixInsight stretches the channels separately, which removes that heavy green or red cast and lets you see the actual nebula or galaxy detail. The Workflow: When to Toggle the Link Why Linear Images Need "Unlinking" Initially Once the
