Pixinsight Lerar Link Direct
Raw astronomical data often has a heavy color bias, frequently appearing green due to the Bayer pattern of color cameras or atmospheric conditions.
Once calibration finishes, clear your old STF stretch. Click the to lock the channels together, and hit the Nuclear button again. Your image should now display a neutral background and beautiful, naturally balanced color channels. 5. Permanent Stretch
With your channels linked and balanced, you can safely transfer the STF settings to the tool to permanently stretch your image into a non-linear state, ready for final detailing. Conclusion
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. pixinsight lerar link
Mastering the PixInsight Linear Link: How to Optimize Your Astrophotography Workflow
The icon (resembling a small chain link in the STF control panel) dictates how PixInsight calculates this temporary stretch across the Red, Green, and Blue color channels:

An astrophotographer could process the image linearly without linking (using masks), stretch it to non-linear, and then link the channels. However, the damage is usually done. Once the histograms are stretched independently, the mathematical relationship between the signals is destroyed. You cannot easily recover the original color ratios after an unlinked stretch. Therefore, the "Linear Link" (applying a linked stretch as the first transformation) is the only way to move from raw data to a viewable image without introducing synthetic color bias.
At its core, LinearFit is a tool designed to match the background and signal levels of one image (the target ) to those of another image (the reference ). This is crucial because the images you capture through a telescope—whether with a one-shot-color (OSC) camera or individual color filters on a monochrome camera—rarely come out perfectly balanced. A sensor's response to red, green, and blue light is rarely uniform, leading to strong, unappealing color casts in your initial data.
PixInsight (PI) is widely regarded as the premier software for astronomical image processing, offering unparalleled power and flexibility. However, its steep learning curve—often referred to as the "PixInsight learning curve"—can be daunting. Whether you are looking for a "lerar link" (learning link), tutorials, or a repository of essential plugins to supercharge your workflow, this guide acts as a comprehensive portal to mastering the software in 2026.

Your image should now display a neutral background
When you first open a raw image, light pollution or sensor bias usually causes a massive color cast—often turning the entire screen bright green or red. If you use a linked STF, PixInsight stretches the dominant color cast right along with the target data, leaving you with a completely washed-out image.
When these steps are correctly linked, ImageIntegration uses the data in the .xnml files to apply a smart, adaptive normalization to each sub-exposure during the combination process. This is what corrects for differences in background brightness and other large-scale variations across your image set.
The Screen Transfer Function (STF) is one of the most powerful tools in PixInsight. It allows you to visualize faint details in your deep-sky images without permanently altering the underlying raw data. At the heart of this tool lies a small but critical feature: the option.
When processing deep-sky astrophotography, your camera captures linear data where pixel values are directly proportional to photon counts. Because raw images look completely black before non-linear stretching, astrophotographers rely on PixInsight’s ScreenTransferFunction (STF) to look at their data without modifying the underlying data.
