Good effort JK. Exposure is about right, but it is not pin sharp, and I think you have overdone the contrast a little, giving the image a sort of harshness. I've attached an image to illustrate my point.[My image is slightly over exposed, but ignore that] It is not as easy as it would seem getting single frame lunar images pin sharp, due mainly to atmospheric turbulence, and to a lesser degree mirror and shutter vibration. I would drop the ISO to around 1000, and use a shutter speed around 1/4000th. A shutter speed this fast is over and done with before any
vibrations can really get going. Also lock up your mirror before taking the shot; one less thing to vibrate. Many of the very best lunar shots are achieved using hundreds of video frames stacked in programs like Registax, as are
most planetary images. For single frames take 10 or 20 and examine each one closely, some will be a little better than others.
