I finally have an updated LHaRGB Image of my previous luminance on M81 and M82, new learning curve was the HDR Compose process in PixInsight, I used this to include the 300S Exposures I had previously that were burning out the core, I may try and get some 60S exposures to narrow the core down even further, but here it is so far:
