Hi Paul,

I've taken a Ha sub with an OSC at 2x2 and found it a lot softer. as you mention, yes, Ha data will only be present in the red channel, so if you take it at 1x1, you'll need to extract the Red and use that as Lum. Atleast that's what I've read and tried.
It'll be interesting to compare a Ha frame at 1x1 from the Red channel and a Ha at 2x2. I guess you could decide after that.
Cheers
