Pixinsight Lerar Link -

Unlinking channels in PixInsight's Screen Transfer Function (STF) allows for independent, non-destructive stretching of color channels to correct for heavy color casts on linear images. This essential initial step enables proper visualization of the raw data, helping to identify gradient issues and data quality before permanent calibration.

Method 2: Linking Data with PixelMath (Advanced "Lerar" Control)

If LinearFit fails (which happens if your noise floor is too high), you need a manual PixelMath link. This is often required for overexposed stars or heavily vignetted edges. pixinsight lerar link

Q: Why is it called “Lerar Link” in some YouTube videos? A: This is likely a phonetic spelling from a non-native English tutorial. The correct terms are “Local Normalization link” or “linear reference link.” The creator may have said “linear link” and it transcribed as “lerar.” Fix: Use StarAlignment process first

From that night on, Elara Vance never published her findings. But every clear evening, she went to the observatory, opened PixInsight, and whispered into the console: Fix: Use StarAlignment process first.

Pro Tip for the “Lerar Link”: Always use the “Show Linked Files” button in WBPP. This visual diagram shows exactly which calibration frame is applied to which light frame. If you see red “X” marks, your linking is broken.

Once linear processing is complete, the image must be permanently stretched. Histogram Transformation : The manual method to "bake in" the stretch seen in STF. Easy Soft Stretch : Part of the Easy Processing Suite
