How do I reduce the green in the background without affecting the galaxy?
Make sure you have neutralize background checked and you can either desaturate the green in selective cooler or if you bring it into Photoshop you can use HLVG, pull down the green channel in curves ro levels, or desaturate and darken the green channel in hue saturation.
Best is to make sure first that the image ia background calibrated, is it? The background neutralization is not what you want to use, this only serves as initial preview to get more or less gray backgrounds in your preview RGB images.
Once you have calibrated the background with the calirbate background tool (or remove light pollution tool) then load it into the HSL selective Color tool, select green push it to magenta (that neutralize it) and you can also desaturate the green color at the same time, so set saturation to negative as far as needed. That should remove it.
If you only wan to remove it in the background, use the range options like background to background + 3*noise, that should prevent the operation to affect the galaxy.
