hi team,
i am working through lots of issues with my system but (very) slowly making some progress (although my mount has other ideas).
can someone advise what they think is wrong with this image?

it is a refractor with reducer/flattener - is it the spacing being slightly off? is it too far out or in?
thanks
Russ
