Ok I tried a bunch of different settings and i couldnt get it just right. Is the bottom and the left side of the moon supposed to look like that or am i doing something wrong? Im not surebut if it is supposed to look like thati can just edit it out but if not then i dont know.

It was taken with a canon s2. shutter - 1/125, aperture - 3.5 (I tried 8 but i think 3.5 turned out the best), spot metering, ISO 50,zoom at 12x, no tripod used, and i also shot from my window because the door is loud when it opens and i didnt want to wake everyone up. I had the glass up and shot through the screen.

your problem is the lack of a tripod at such a long focal length...

at full zoom of the s2is, even with the image stabilizer on, 1/125 is just too long of a shutter speed to get a sharp pic.. hence you see the softness around the edge from the camera shake...

so use a tripod, or even prop your camera up on a pillow or bean bag, i think you will be quite a bit happier w/ your results...

Dustin, I have a different take on this. See the top right appears to be much better focused than the lower left. And by comparison, much more acceptable. My guess is that the angle of the camera lense was not 100% square to the screen of the window. I believe this accounts for the offset blur. Maybe tho, the blur at the top right just isn't visible since it's offset toward the better lit portion of the moon. In any case, a tripod is definately the first correction. 1/125 with a tripod is manageable and worksnot too bad. Look at this one with my Panasonic FZ 30. It's 1/100 and f 8 (maybe even higher like 9 or 10 I know I played around with it a bit but shutter speed is in that range)...hmmm ya, went back and reread the post. Actually the blur is most likely exactly what you suspect. yup. Good case for a tripod, good call Sherlock! Best regards,

looking at this again, it could also look as such if he shot before the image stabilization fully stabilized.. maybe?... either way, tripod or some kind of support is needed for most ppl at those shutter speeds...

kenneth- though i must say you did a nice job with your pic at 1/100.. you are a steadier man than i....

Now comes my other hobby, astronomy... Well a tripod might not help especailly using ISO of 50, and focal length, wound only make it worse unless it is a tracking telescope. The earth is moving and the moon is moving. If you are having a semi-long exposer of lets say 1/50, it will appear that there is camera shake. If you tack that Baby on to to telescope of a long focal lenght a shutter speed of 1/125 might be a little blurry, or appear to have camera shake, if you have access to a robotic telescope with a camera piggy back then that is your best tripod the camera will move with the telescope to track the moon.

the moon/earth movement is enough to show up as blur at shutter speeds of 1/50 or 1/125.. ????

Yes and the more you increase focal lenght the more it is magnified. In astronomy looking through a non robotic telescope some celestual bodies say in the veiw finder just a few seconds,
