Sorry Dave, I'm not much use to you.
Centre top one was my first impression, but as I looked closer I found each one highlights detail in a different part of the image better than the others. For example, I reckon the centre top is best for the detail above the GRS in latitude. The RH one is best for the detail in the bottom red band, etc. So now I'm all confused and can't decide!
Great image(s) BTW!
I'm using a 19" Samsung LCD BTW.
