Can you zoom in closer? ISO speed slower?

You need to open the aperture up some on that, and slow down the ISO. It looks like it was a full moon, so I wouldn't shoot with anything smaller than f/16.

Here is a shot and my info.

The moon, particularly a near full moon, is an extremely bright object. Here's one of my recent efforts:

The reason for the flare and star effect is that the moon is WAY overexposed. This is OK if that is the effect you are after. I have used it myself.

Shutter priority is not what you need here, not is ISO 1600. Switch to manual, use ISO 100 or so, and expose at around 1/120s at f/8. This will give you reasonable detail in the moon's surface. These settings are just approximate, and you may need to adjust up or down somewhat, depending on local conditions.

This came up on another forum recently. Expose it as if you were going to expose something you were shooting at noon on a sunny day. It is, after all, being lit directly by the sun without obstacles/shade. It is the vast amount of dark sky which makes this seem a little wrong at first. Use sunny 16 or something.

You know after looking at your original post again, it may be that we are concentrating too much on the moon portion of the photo and not looking at the "big picture". If you want a moon shot our advice is good, but if you want to show the moon over a landscape, our advice is incomplete. The exposures you used captured the landscape pretty good, but you need to get rid of the star effect and the flare. You would then need to photograph the moon using the some of the advice we've given and then edit the two shots to get the total effect you want.
