removing LP from an astro image

Not sure if this counts as a tutorial, but I gave a demo / workshop to our local Astro Soc on a 'beginners' approach to removing light pollution from an astro image.
Based on a tripod mounted 10s image, it uses Paint.net software (most suitable for absolute beginners as it has an easy learning curve and is free, so no investment needed). The same basic principle can be applied by users of other software
I'd appreciate feedback.
