What ISO? What shutter speed? When I increase the size of my browser window to get a closer look at them, it looks as though you tried to sharpen using Unsharp Mask or High Pass Filter and over did it. Are these also cropped and enlarged? cropped, but not enlarged. cleaned up with LR3.

F stop of 5.6 and shutter speed of 1/200. i'll try to squeeze out something better with LR3 again. Can you post the original untouched? Tim Kerr

this is a resized jpeg. i'm figuring that i need a decent tripod instead of pickup cab.

Focus looks good enough, but, since it is a reduced size Jpeg I cannot make it look good and enlarge it to the same size as your cropped version of it.. For that, I would need the Original RAW image.

My recently posted 1/4 moon was at 1/1000th sec hand held. Peter

My recently posted 1/4 moon was at 1/1000th sec hand held. You dont NEED a tripod but it can really help. Between using a tripod, remote shutter release, and mirror lockup every little bit can help you eek out a little more sharpness and let you blow the image up even larger. Plus using a tripod allows you to manually focus on the moon, which is pretty much required if you want to have a good focus, as the camera's autofocus isn't going to be perfect on the moon. The moon has several different focal planes as well, as it gets towards the edges it is farther from us so the focal plane changes, so you really need to manually focus the image in order to get the focus as sharp as possible where you want it.
