Nice shot! That's a target I fumbled with this year.

Thanks Eric. My first time imaging this target. I'd like to get more data to help bring out the blue color more.

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.
