NGC 5128 Ha (brief test)

Wanted to do some testing with my QHY163M (QHY version of the ASI1600) and as we've had nothing but clouds and fog... I decided to image through the fog and near full moon over two nights.
At the moment I am trying to figure out where I am getting some tilt, not yet sure whether it is in the focuser or camera (different screw connections than I was using with the ASI1600). Looks like it'll be at least a week before I'll be able to do any more testing so I'll just leave this where it is at the moment. Wanted to shoot something in the middle of the Milky Way but the moon has been sitting right dead centre in that field!

This is 23x400s at Unity Gain. All subs were fog effected, didn't look too bad in the back yard but could see it as I looked at the lights next door. Relativity humidity must have been something shocking as my scope cover was wet by 5:45pm!
Culled most of the subs taken, used the Subframe Selector and just the ones that had the most stars. Kept all with 2,600-2,000 and culled everything with less than 2,000

Mostly just wanted to see if I could get the jets to show, didn't think I'd get much of anything with the fog!
