Nice detail, but for some reason - I don't like that shadow effect on the left side of the image?

It signals some issue with black point during processing perhaps (I might be wrong).

Do you apply gamma 2.2 to your linear data?

Interesting you saying that i normally do a histo stretch on all panes before assembly. On this occasion i did not. Might experiment building again at some point. I did apply a little gamma lift post processing if i remember. I have issues with a huge street light shining into the scope. Affecting the background. So i also darken the background it may be this you are seeing i will have another look. Thanks for pointing it out.
