But if you dither and collect enough data (more than about 16 frames) then you can stack using the Bayer drizzle algorithm which will use the dithered subs to basically remove the loss of resolution from the Bayer array. Isolating the red channel at this point you haven’t lost as much resolution thanks to the drizzle.
I’m still learning but using the above has definitely improved my Ha data.

Thanks for the hints Paul. I already dither but have a long way to go with processing.
