Tarantula Nebula HaOIIIRGB

After many many many revisits I think I finally have this data set (well two) where I'd like them to be.

Telescopes:
RH200
Sky Rover 130mm

Cameras
QHY163M
Nikon D810

Data
70x300" ISO400 (Sky Rover)
Astrodon 3nm Ha: 44x300" (RH200)
Astrodon 3nm OIII: 60x300" (RH200)

There is oh so many ways of combining narrowband to RGB and depending on how it's done changes the way both Ha and OIII colours turn out. Even the order of some steps changes the colour balance. PixelMath is my friend, it's a good friend that sometimes turns around and slaps you in the face

It's always a hard decision of whether or not to resolve the core of NGC2070 but I decided to keep the dynamic range. It is a little brighter than I'd originally wanted but it does look too flat otherwise.
