This was my attempt. My red frames suffered from a calibration issue, probably darks were scaled incorrectly, or offset was wrong. The red frame has very low dynamic, so stretching its range leads to a stair effect and halos being unnecessarily emphasised. It's not the first time I fail a project for this reason, but I have not found the root cause yet.
Also, I think that framing is important on this target. There are very interesting structures around, and rotating and shifting the sensor to catch them - or creating a mosaic - makes it a nice challenge.
