Beginners often forget to link their dark flats to flats. If your flats and dark-flats have different exposure times or temperatures, WBPP will fail to calibrate the flats, leading to over-correction.
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.
Cause: Local Normalization was not linked across panels. Each panel of a mosaic needs its own LN reference because the background flux differs.
Fix: Run WBPP separately for each mosaic panel. For Panel A, use a reference stack from Panel A. For Panel B, use a reference stack from Panel B. Never link Panel B lights to Panel A’s reference.
To use PixInsight effectively, you often need external scripts not included in the base download.
If your target has a light pollution gradient that the reference does not, LinearFit will fail because the background sky is not uniform.
The EzLinearFit script (part of the EZ Processing Suite) is widely used. It automates the "Lerar Link" across up to 12 images simultaneously.
If you’ve spent any time in the world of deep-sky astrophotography, you’ve likely heard the term LRGB thrown around. It is the gold standard for capturing true-color images of nebulae, galaxies, and star clusters.
While capturing the data is half the battle, processing it in PixInsight is where the magic truly happens. Specifically, the LRGBCombination process is the bridge that merges a high-contrast black-and-white image with a lower-contrast color image.
In this guide, we will walk through the workflow to create a vibrant, high-definition image using PixInsight’s LRGB tools.
Searching for “Lerar link problem” on forums yields three specific errors. Here’s how to fix them.
The LinearFit process (found in the IntensityTransformations category) is the closest native tool to what you described. It computes a linear transformation (y = a*x + b) that scales the target image to match the reference.
