I recently published a well-received version of M81, it seemed rude not to process its compatriot.
In order to realise all the details you could argue the image is actually a L, L, L, L, L, L, L, L, L, L, Ha, Ha, Ha, Ha, Ha, RGB, RGB, RGB, RGB, RGB, RGB, rather than just a HaLRGB image!
In order to realise all the details I have been persisting with my (very time-consuming approach) of building the main layers from multiple stretches of the main frames from very dark to very light, a manual HDR (but with full control) most of the work is done in PI but the layering and masking has to be done in PS for control. I am finding at the longer focal lengths this really lets me realise all details from the dark (often washed out by brightness on such targets) to the very light, I can even stretch beyond the limit to realise the fainter details.
Anyway, hope you all like - not a quick process taking about 8 hours solid to process over a few days.
As well as realising some great detail I was pleased to see the inner structures showing well including the mushroom shape to the right and the double boundary of the left side (inner ring just about visible)
