Link — Pixinsight Lerar

Apply a slight Pedestal (e.g., +100 ADU) to both your reference and lights before LN. In WBPP, under the “Light” tab, set “Pedestal” to 100 for all lights.

This is the "Lerar Link" you have been seeking. It creates a mathematical bridge between the channels so they can be combined harmoniously via ChannelCombination .

Mastering Local Normalization is a hallmark of an advanced PixInsight user. It may seem complex, but understanding it comes down to one concept: This is the deliberate act of feeding the .xnml files produced by the LocalNormalization process into the ImageIntegration process. Once you understand this link and the importance of working with linear data, you have a powerful tool for producing cleaner, more professional astrophotography images, regardless of when or how your data was captured.

icon (represented by a chain link button in the STF window) determines whether PixInsight calculates the auto-stretch for each color channel (Red, Green, and Blue) identically or independently. Linked vs. Unlinked: When to Use Which Linked Mode (The "Link" is On): pixinsight lerar link

You should now see a significant increase in detail and contrast compared to your original RGB image.

Mastering the PixInsight Linear Link Feature: A Deep Dive into ScreenTransferFunction and Color Channels

If you click the standard on a raw image from a One-Shot Color (OSC) camera, your image will often turn intensely green or pink. This happens because sensors (especially those utilizing an RGGB Bayer matrix) feature twice as many green pixels as red or blue, causing the green signal to dominate the raw histogram. How the "Link" Button Fixes This Apply a slight Pedestal (e

Clicking the chain icon breaks the link. When you click the nuclear radioactive auto-stretch button with channels unlinked, PixInsight analyzes the Red, Green, and Blue channels independently. It aligns their background histograms perfectly.

Alternatively, it could be a phonetic misspelling of – an acronym that doesn’t exist. The most actionable interpretation is “Linear Reference Link.”

For those using monochrome cameras, LinearFit is even more critical. The luminance (L) channel is often far brighter than any individual color channel. Applying LinearFit to match your R, G, and B channels to the L channel can create a more harmonious dataset before combination. It creates a mathematical bridge between the channels

Raw astronomical data often has a heavy color bias, frequently appearing green due to the Bayer pattern of color cameras or atmospheric conditions.
