Now that I have made the switch to AP I am re-working many of my astrophotography macros.
I will share them here with brief instructions and encourage others to share theirs.
All my macros are for Windows OS
This set of 3 takes the basic individual monochrome filtered R G and B images and converts each into a colour channel.
Load each RGB file separately into AP, Run the respective macro and copy the output of each into a single AP layered document, then set the blend mode of each to add
This will output a single RGB non white balanced file
grey to blue.afmacro
grey to green.afmacro
grey to red.afmacro
