Last night was kind weatherwise. Here is a widefeld of the Antares region. I just squeezed all the colour I could out of the data. The good thing about modded cameras is the noise in the red channel does not show when enhancing H alpha regions.
The other trick I have discovered is when combining in Registar use the median rather than average and any 'dark' noise pixels (from the in camera noise reduction) disappear.

Details Canon 5DH,300mm@F2.8,8X240s ISO 800, LPR filter. in cam noise reduction on, VR & GX and the usuals in PS lots of times to squeeze out the colours you see.
I am slowly getting the hang of this. Still have a lot to learn.
