Ahaaaa Chris, see, it must have been an options thingy. I was thinking about the H and L values, but I thought those were automatically calculated.
They are automatically calculated if you have set the correct:
1. Telescope Focal Length
2. CCD Pixel Size
If you're using a DSLR, you must set the CCD pixel size yourself as it is different for each camera.
I did set these correctly, at least the FOV that is also calculated and displayed in the window was giving a correct number.
I'll pay attention to the numbers in the command line next time to see what is going on exactly
In the meantime; is there any other place to edit the CCD settings other than the Image Info tab?
