Thought I have a go at narrowband imaging.
Only managed to get 2x10 min subs in Ha before SGP stopped working (I think I resolved it now).
A quick stack and a gentle stretch.
ASI1600mm and WO FLT 110 with 0.8 reducer/flattener.
Still some star distortion towards the left hand side of the image, I think it's tilt, but others may know more.
Aim to get more data soon.
Thanks
