It was hard to get the 'blue' area to show and it made the 'red' area look peach colored . Centering the image better might help but I was trying to see how far the 'blue' would go . The image is the original size as Bin1 and cropped slightly on the edges . z
Hi Robert, keep working on these images, you're definitely improving. The image histogram is clipped at both ends - somewhere in processing, about half the dynamic range was lost (eg the range from darkest to brightest). Also, it looks a little soft - perhaps there are some images that are a little sharper, and you could eliminate them, or sharpen the finished product. For fun, I adjusted the .FIT with Screen Stretch and then Saved As a JPG with Manual Stretch, Screen stretch. This makes better use of the available range. There is a lot more to experiment with. Keep the images coming!
