I use mine binned for Ha & RGB.
Maybe I should change & use 1x1?

I am still undecided about binning.
Binning at 2x2 should increase the signal to noise ratio according to studies I have read.

Also -
Think about it -
if you use narrow band such as Ha then you can pick detail out that is lost in a Luminance image.
Also you can image in light polluted skies with narrow band & still get top results.

Why not consider RGB as a form of narrow band?
Why take Luminance at all in light polluted skies?
If you just took RGB at binning 1x1 & made a pseudo luminance frame from it
then you would get better signal to noise ratio in light polluted skies.
I will try this & I have already noticed when I process that if I use 100% Luminance
in Photoshop then the image is worse.
I usually have to reduce the opacity of the Luminance frames.
