: Applies the same stretching parameters to all three color channels simultaneously. This is the default but often results in a heavy green or red cast if the background levels are not naturally balanced. Unlinked Stretch (Lerar/Link workaround) : By clicking the STF icon while holding the
The goal of the LRGB process is to "map" the high-quality detail of the Luminance channel onto the color data of the RGB channels. pixinsight lerar link
To see your data without permanently altering it, PixInsight relies on the . Within the STF process lies a small but powerful tool that dictates how you view your raw data: the Link/Unlink RGB Channels function. Understanding how this setting interacts with your data—and knowing when to use it—is a foundational skill for clean image processing. What is the "Linear Link" in PixInsight? : Applies the same stretching parameters to all
You should now see a significant increase in detail and contrast compared to your original RGB image. To see your data without permanently altering it,
To get the most out of your data, integrate the linear link toggle into your standard PixInsight preprocessing workflow using these steps: 1. Initial Inspection (Unlinked)
Now for the main event. We are going to combine the Luminance (L) image with the RGB image you just created.
Here is a simple, practical workflow for using LinearFit on a standard OSC image:
