PixInsight LERAR Link — In-Depth Guide and Tutorial

Tips for Effective Learning

• Start Simple: Begin with basic processing steps before moving on to more complex tasks.
• Community Engagement: Interact with the PixInsight community through forums and social media groups.
• Practice: The best way to learn PixInsight (or any image processing software) is by processing images.

Step-by-Step Guide to Linear Linking

Step 1: Choose Your Reference Select the best frame of your dataset. Usually, for RGB imaging, the Green channel is the brightest. For Narrowband, Ha is often the reference.

Step 2: Open LinearFit

• Navigate to: Process > IntensityTransformations > LinearFit.
• Click the blue "New Instance" icon to drag the triangle onto your workspace (or apply directly).

Step 3: Set the Reference

• In the LinearFit interface, you will see a Reference Image dropdown.
• Select your reference image (e.g., "Green_channel" or "Ha_master").

Step 4: Apply the Link

• Drag the LinearFit process triangle onto the target image (e.g., Red channel).
• Result: The Red channel now has the same median brightness and contrast range as the Green channel without clipping.

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. pixinsight lerar link
