Excellent image Mike! Love that detail!
It's not too hard to calculate the resolution for each setup Mike. With the ToUcam on my C8, each pixel of a moon image is about 1km at
f/10, 500m at
f/20 and 400m at
f/25. Of course that's round numbers, and the moon's orbit is elliptical, so it does vary a bit but not significantly enough for a general scale on an image. If we were trying to do some precise science with the image that would be a different matter!
