    What is the focal length used ? It would be better to show us the photo.

    for such shots, it prob would be better to use a smaller aperture and set hyperfocal on the lens rather than using AF. works pretty well for me, but could be a little difficult if your lens does not have a distance scale.

    Hi,

    I did what you did a few days back. I found thattThe blurness of the moon is caused by overexposure. You could try shooting at higher shutter speeds, but your scenery will be compromised (become underexposed).
    Maybe you should think of photoshopping...

    yup... have to remember that the moon is constantly rising. so shooting at 0.5", the moon have risen a bit. that may explain the blurness in the moon.
    You are who you are. Shoot what you enjoy.

    Good point to note.

    i think that the problem caused would be over exposure from the moon. the moon is a lot brighter than the rest of the night scenary.
    in this case, u can try adding a grad ND filter...

    0.5" will not make much of a difference unless you are using >400mm. The blur is actually due to the blooming caused by overexposure.

    i tried taking a shot of the moon yesterday.

    1/50s shutter speed
    f/22 aperture
    85mm focal length
    iso 100
    tripod

    quite sharp except image of it is super small. using a telephoto help heaps.

    i also learnt that for night landscape shoots, use manual and set aperture very small for sharpness. even at f/16, i could not have sharp shots. i had to test a lot of settings.

    Full moon not nice to shoot.. Too bright and not much details. Half moon better because the light comes at an angle, accentuating the ridges etc.

    Here is a 50% crop, not very sharp moon image shot through a Nexstar5 scope.

    I think might be some clouds too. Looks like there's something around the moon. Still the moon is definitely overexposed.

    Your photo shows that the moon is definitely overexposed and buildings are underexposed. There is no way you can have both the buildings and moon in same exposure except mulitple exposures or photoshoped with different exposured.

    Hmmm, maybe you need flash to freeze the moon .

    Yes, it is difficult even with film camera to capture moon in wide angle scenery. It is always overblown if you want to capture the scenery detail. And the moon is always too small in the scenery to make it looks good. It might better to exclude moon on night scenery.

    Regards,
    Arto.
