Managed 1 hour and 50 minutes worth of Ha through my QHY9/FLT98 combo. (The last 10 minutes was lost due to cloud)

Will aim for another 2 hours worth and then start capturing some LRGB data to add some colour.
Cheers for the info about the composition, it did look like there was more above. I originally had it vertical to the camera which was cutting off both ends of nebulae, so I had rotated the camera to where I had guessed the 'correct' orientation. Was close!
