There is dust that stands out hugely in my red channel that almost does not show in your HA, but then the dust lanes in the middle of the nebula are a lot sharper in HA only than my red channel.

Your comment Paul about the red showing up much more prominently in your image triggered my curiosity, so I dared to put two images side by side to identify the area of your red channel not showing in my Ha - honestly I am not sure which red area is not showing in Ha. But your image shows so many more stars!

Dare I say as sharp or perhaps even sharper than an FSQ?
Your tracking is a little off and that pulled down what could be an even sharper image. Perhaps a tad of PS sharpening that corrects for motion blur?

Thank you Greg. I am suspecting my FTF having a bit of play, because this tilt disappears completely when taking subs with the scope pointing up vertically, while it is most noticeable when the scope is pointing closer to the horizon.
