This evening I’ve been playing with my Nikon D200, Sigma 28-300mm F3.5-6.3D Macro lens and manfrotto tripod and in tribute to Patrick Moore, here’s a picture of the Moon (sharpened to get every last detail out and cropped), a subject dear to his heart.
OK, ok.. I know, but it does bring out the central peaks of Tycho and Copernicus which cannot be made out from the original image.
I used the “Unsharpen Mask” tool with a radius of 1 pixel and 500% to make the detail visible.
PS
You can see the untouched (other than cropped) image here.
