Exploring Pixinsight Narrowband Normalization Techniques
Method 1: Warren Keller’s Simple Approach
Learn how to unlink channels in PixInsight’s Screen Transfer Function (STF) for better color balance, reducing the dominant green hue from Hydrogen Alpha.
Method 2: Linear Fit
Explore the Linear Fit process to normalize channels, using O3 as the reference image to achieve balanced colors across S2, HA, and O3.
Method 3: Bill Blanshan’s Pixel Math Method
Discover Bill Blanshan’s pixel math expression for narrowband normalization, using offset scaling to match O3 and S2 to the HA signal.
Each method offers a different approach to achieving more balanced colors in your narrowband astrophotography, providing flexibility based on your workflow and desired outcome.

Is there a link for the Bill Blanshan script.
Hi Mick,
Hopefully by now you may have got the information you need, in case not, then in your browser type in either:
Bill Blanshan
(this should provide a link to his YouTube channel name, or, type in the YouTube channel name in the browser instead:
AnotherAstroChannel
Either should provide access to his channel.
In all his videos he details how to use them as well as where to download each process/script from.
In David's comment below he mentioned that Bill has since made available an excellent process, Narrowband Normalization, highly recommended. You'll find in his channel a video for that and as with all he provides a link. You'll see others as well, the Star Reduction script I use regularly.
CS, Ray
Why didn’t you use the new Narrowband Normalization Process in Pixinsight that was developed by Bill Blanshan?
