I can't seem to get my mind around Pixinsight pixel math. Having split the channels of my OSC image I would like to combine Green and Blue and create a mono image to combine with my Ha.
Sounds simple but...
What is the expression that would accomplish this AND how do I enter it in the pixel math dialogue? I found some pm examples online, but those users assume more knowledge than I currently understand.
Thanks for any pointers you may have.
