EdgeHD 14" on Eta Carina

I have finally managed to find a way to image with my EdgeHD 14" at a ratio between 6 and 7 and without re-introducing coma into the train. The target is an obvious one for this sort of testing - Eta Carina - and here is the result of finally combining this scope with an AstroPhysics reducer (the CCDT67). I present it in 2 different processing forms. Both are full-frame and 10 x 3 minute subs. Camera is a QHY8. Mount is a Titan.
I can't decide which I prefer.
